Enough surfing, now go back, to your own.

The video content of this page works with Windows and has WMV (Windows Media Video) format. In particular you should not experience any problems with Windows Media Player and a variety of browsers (Internet Explorer, Firefox, Chrome) on Windows XP/ Vista/ Windows 7. Other operating systems (e.g Apple/Mac or Unix) are not compatible with the videos without additional software.

How to view the videos on MacBook.
Suggested by Kevin Tabien Sept 2009.
1. Download MPlayer . Get the OS X 1.0 version.
2. Download DLL files . Get the file ( or the most recent version).
3. Go to finder in the tab go, click the "go to folder option" and type "/usr/lib/" in here you will make a new folder called "win32". You may need to type in password for your computer and become administrator as the "usr" folder is hidden and writing or modifying files here can cause issues so only do what is needed. If you do not fee comfotable with this ask at the computer help window in Maes Building.
4. In this folder you will extract all the contents of the downloaded zip file.
5. Last is opening MPlayer and going to preferences and changing the video out put model to quartz/quicktime.
6. After all this just open the files using MPlayer and they should all work.

Here you will find the daily lectures. Clicking on any video link on Windows opens up windows media player (WMP), or a designated compatible player, on your computer and starts the presentation. A typical video file is about 20-30 MB and takes about 3 minutes on a basic DSL/Cable line to download. Maximize the window size for WMP and adjust the volume. You can scroll back and forth in the file (up to the point it has been downloaded). You can also use the fast forward. To save the file for viewing at a later time (for example in case you have a dial-up) Right Click and use Save Target As.

(1) Computers, like everything else in life, eventually break down, by age, accidents, poor design, or malicious intent. The first line of defense is to have a back up copy of all personal files on several media as well as installation CDs and serial numbers of various software in case you need to rebuild your machine or file system.
(2) Multiple Internet security software products may be incompatible with each other. Investigate the safety of any software, including security software, before installation.
(3) Links to commercial sites here are not endorsements of their respective products. Do not give personal info or purchase any subscription.
(4) Assume your activity on computer is monitored. Assume posted personal information will become public.
(5) Prolonged time spent in front of a computer or a similar device or setting is unhealthy. A long list of serious medical problems are associated with such a habit (heart, eye, posture, weight, repetitive motion injuries, and addiction may result). If you have to spend substantial time at a computer make sure your workstation is designed properly and take frequent physically active breaks.

Errors and typos do occur in these lectures. I appreciate if you bring them, and any other suggestions you have, as well as a list of malfunctioning links, to my attention. After some videos you may see a Correction notice related to such errors.

To improve your experience with this course consider the following:
(1) Take notes while you view the videos, as in a traditional lecture.
(2) Pause the video, try to solve the presented problem by yourself, and then compare your solution with the presented solution.
(3) Become part of a study group.
(4) View the lectures on a large screen monitor, perhaps with your study group.
(5) Participate in class presentation.
(6) Pause the video when you need to take a break. Use fast replay if the lecture is slow.
(7) Make flash cards by noting solved problems you have studied (in videos, class, text), note the location of solution on the card, and time required for writing the solution anew from scratch. Store the flash cards in a box. Every week give yourself a timed test by randomly picking about 7-10 cards from the recent collection. Review the sections where you did not reproduce the solution correctly. Try cumulative tests once a month.

Does hybrid style work?
An experiment was conducted in 2006-7. The students who took Calculus 2413 in fall of 2006 were tracked into spring of 2007. Those who took the hybrid format section in Calculus I had an average* of 2.25 in Calculus 2. The others had an average of 1.65 in Calculus 2.
Some of the possible explanations for the significant improvement of the grades of the hybrid group are:
1- Higher time requirement.
2- Statistical fluctuation. We did not have data on the student backgrounds. It is possible that this particular class had substantially better preparation from the start. At a minimum we either needed the result of a placement test or data on the number of students who had taken calculus in high school.
3- Placebo effect. Also known as halo or pet-project effect.
4- Class participation. It is known that moderately high levels of adrenaline can make a lasting impression of events in your brain. That is why you remember traumatic or pleasant events for a long time. A class presentation typically causes some levels of anxiety, and hence moderately high levels of adrenaline, for the prepared presenter. Hence the student is more likely to retain the material and perform better in the long run.

* The average was obtained by setting, A=4, B=3, C=2, D=1, O=all other grades(F,Q,W,NG,I,...)=0.
For comparison and calibration the grade distribution of the hybrid group in fall of 2006 was set to be similar to the distribution of grades of all students in Calculus I fall 2005. None of calculus II classes were of hybrid type. There were 40 students in the hybrid class and 180 students in total.

The downsides of hybrid style
The most common objection that students have to this course is "But I won't be able to ask my questions." This results from two misconceptions.
Misconception 1) This is an online course and in these courses communication with the instructor is a chore, or worse he is nowhere to be seen or heard of. But, this is not an online course. Classes are held as usual, and you have plenty of time to ask questions.
Misconception 2) In a traditional class I can always raise my hand to ask a question. But students typically don't feel comfortable to ask questions in the middle of a lecture. Realistically, a typical class has 40 students and lasts 50 minutes, rendering a question/answer format un-workable. With the video format you can pin-point your difficulty and discuss it with your instructor in the recitation or office hours.
That said there are downsides that you need to know about:
*) You cannot ask questions from the instructor in the middle of a video lecture.
*) This course does take more time initially compared to traditional lecture format. But you will have a stronger foundation for the long haul.
*) Most students are accustomed to being taught in person and in a social environment, sourrounded by classmates. A few students are accustomed to being instructed by reading a text. The video format is, psychologically, an experience somewhere between the two. You need to get used to it.
*) The video lecture is slower that traditional lecture. This is partly caused by the hardware. Use fast replay to adjust.
*) The field of view is small. A typical computer screen is only a small fraction of the blackboard. This causes a tiring flipping of pages or scrolling back and forth. Videos are immense cpu and memory intensive applications and this shortcomming has not been resolved by the current technology.

The videos do not have subtitles as yet. At this time hearing impaired students need an interpreter to view videos.

This course is for students in math, engineering, physics, computer science, biology+psychology, biology+chemistry, chemistry, biochemistry, forensic chemistry. Some students from other disciplines may be required to take this course as well. All students are graded on the same basis even if they decide to change their major.

The following lectures were based on Calculus, Early Transcendentals, 5th edition, by James Stewart.

We will cover most of Chapters 2-6.
Chapter 1: Precalculus, review as needed.
Chapter 2: Limits and Derivatives.
Chapter 3: Differentiation Rules.
Chapter 4: Applications of Differentiation.
Chapter 5: Integrals.
Chapter 6: Applications of Integration.

Homework Assignment:
Do what you can.
Do at least one problem from each basic problem category.
Do another in case you had a hard time with the first one.
Redo problems in lectures, classes, text.
Prepare self-test problems by writing them on flash cards and entering where the solution is to be found.

Weekly Time Requirement:
For Fall or Spring Semesters:
4 hours to view the videos.
4 hours to do the homework.
4 hours to attend the classes.
For compressed Summer classes:
6 hours for each category.

You have several resources to help you decide the courses you can take:
General Catalog, advisors, instructors, textbook, first chapter, first few lectures and tests, classmates, upper-class students, Internet, etc.
It is essential that you allocate substantial effort to make sure that you are spending your time and energy in a beneficial way.

Official Policy/General Catalog description: Prerequisite of 2413 is grade of C or better in Pre-Calculus MATH 2312, or its equivalent.
Prerequisite of 2312 is: Grade of 270 or better in Math THEA or C in DMATH 0372. If THEA exempt then prerequisite is 500 MATH SAT or 19 MATH ACT.

The following is an instructor's personal opinion on prerequisites for 2413:
Short Version:
Take College Algebra (1314), Trigonometry (1316), and Basic Calculus (2376/1325), then take Calculus (2413).
Long Version:
2413 is essentially an open admission course. This cuts both ways.
Students come to this course with a wide range of preparations:
AP Calculus or CLEP Calculus, or
High school Calculus, or
Calculus for Science (2376) or Business (1325), or
College level Algebra (1314) and Trigonometry (1316), or
College level Pre-Calculus (2312), or
High school level Pre-Calculus, or
High school level Algebra and Trigonometry, or
High school level Algebra.

Your chance of success is higher at the top of the above list and decreases as you come down the list. There is a major gap between those who took some form of calculus before and those who did not.
You are encouraged to make sure that you have taken the equivalent of following courses before attempting Calculus I, 2413:
elementary arithmetic, geometry, algebra, trig, -and- college algebra 1314, trigonometry 1316, and basic calculus 2376 or 1325. Notice that this is a non-standard recommendation. These courses do not count toward majors where 2413 is required.
Red Flags: OVER-reliance on any of the following items in your educational path is a cause for concern:
Multiple-choice tests, work sheets (used in place of lectures), short work sheets (where all you do is to write a final answer and do not really show work, so you do not practice writing or presenting math), memorizing from simplified handouts and notes (as opposed to reading and understanding substantial texts), using calculators, skipping math courses for a semester, absentee teachers, substitute teachers, teachers who were not certified, teachers who were not math majors, classes where everyone passed the course, classes where much of the syllabus was not covered, and social promotion.
In above cases, it is more prudent to start with College Algebra 1314, follow with Trigonometry 1316, and FINISH the entire syllabus on your own in each case. Then take 2376 or 1325. Then approach 2413.
Notice that most college algebra classes are not intended to prepare students for calculus. (Majority of students in these classes will not take any advanced math course, so the course does not expose students to level of algebra needed for calculus.) Even Precalculus 2312 does not properly fit the requirement since it is only an abbreviated combination of Algebra 1314 and Trig 1316. And again, many students in 2312 do not intend to go to calculus. That is why you need to spend the extra effort on finishing the syllabi of 1314 and 1316, and/or, take 1325 or 2376. Note that 1325 and 2376 do not have any trig components.
In fact, once you miss the advanced math track in high school it is a substantial struggle to catch up and get back on it in university. However, if you like the math-centered sciences then it surely pays to spend this extra effort.
There are several levels and styles of understanding mathematics. At the highest level, math is a result of direct intuition. Next, it can be the result of studying mathematics texts. More commonly, it can be the result of listening and viewing drill oriented presentations, similar to what you see in the videos here.
As such, this course falls short too, and presents you with at least one red flag since it does not emphasize the reading of any text. If you are interested in mathematics you must get used to reading mathematics texts. Then you should to do some of the challenging exercises. Then you should try discovering mathematics.

Students from Texas Academy of Leadership in Humanities, or any other accelerated program, who have successfully passed a calculus course in high school, are encouraged to take Calculus 2413. All other students from TALH are required to consult with the instructor before taking this course. Please read the section on Prerequisites, above, carefully.

You can search this long page for a mathematical phrase to find an applicable video. Use CTRL F to open the search box for your browser. Each browser also has its own "Find in Page" option. Search is exact, similar to what a basic word processor provides. There is usually no spelling suggestion facility.

Software Requirements:
The following free software will be needed. They are usually already installed on a new computer.

1. WMV files (all video lectures) require Microsoft's Windows Media Player, or any one of the many compatible players. Version 10 has a better fast forward function than version 11. Version 12 is also out.

2. PDF files (class information) require Adobe Acrobat Reader. Be aware: Adobe Yahoo! Toolbar and Adobe Photoshop may be automatically included in the download as well. Uncheck the boxes for those options before downloading.

3. JAVA applets (extras) require Sun Microsystems Java Runtime Environment (JRE). (Once you are in an applet page click somewhere on the demo and look for a slider or a point that you can grab by mouse and move it around. Or there may be an input box where you type in a formula and the page responds by analyzing your input.)

4. FLASH files (extras) require Adobe/Macromedia Flash Player.

You may find the following viewers useful if you browse Internet for course related material. Note that commercial players may try to associate various file formats with their own software.
testing your browser pluggins
Mathematica Player
RealPlayer Caution! Main site tries to get you to subscribe to various unrelated software. Be careful! Instead you may try a more reasonable download at BBC .
Geomview for Mac OS X, UNIX, CygWin

Computer Labs:
1. Gray Library Media Room, 7-th floor, can borrow a headset, very crowded.

2. Computer Science Department labs, MAES Building, 2nd floor, bring your own headset, not so crowded. (Do not confuse that lab with the Writing Center Lab next door.)

3. Mathematics Department Lab, Lucas 209, bring your own headset, not crowded.

Policy Announcements:
1: Calculus as a hybrid / U-Try style course. Description of the general format, policy, schedule, benefits, and requirements for the course from Spring 2010. New policy will be announced.

2: Writing Requirements for calculus. Good handwriting, good exposition/presentation, and good mathematical grammar count heavily. Here is a sample of common writing mistakes that should be avoided (if you want to be taken seriously!).
a) Putting an equal sign between items that are obviously not equal.
b) Missing one side of an equation or not putting an equal sign between the two sides of an equation.
c) Misaligned equations.
d) Small handwriting.
e) Missing paranteses.
f) Missing operation symbols (e.g., limit, derivitiave, integral, d/dx, ' , ", etc).
g) Missing relational symbols (e.g., =, <, >, etc).
h) Use of blunt pencils. Bring three already-sharpened pencils to tests.
i) Multiple answers or not clarifying your final answer.
In addition:
Show all work. All algebra and calculus related work must be exhibited. Use one or two columns to present solutions.
If blank space is provided on exam paper then you are expected to write your solution next to the problem.
Scratch sheet is mainly for trial and error or a first draft. It is not intended as the final resting place for solutions. If you run out of space and use the scratch sheet for your answers then do put your name on it and refer to it on the exam paper. Put loose sheets, such as the used scratch sheets or formula sheet, in the middle of your exam and return all pages to the instructor.
If blank space is not provided next to questions then additional blank sheets will be given. Write your solutions on additional pages in order and label each part. If you want to skip a portion of a problem, and come back to it later, then start the next question on a new page to be able to keep the pages in order. Put exam paper on top and staple all papges including the formula sheet, if any. Make sure you do not write where you expect to staple.
Please put un-used scratch sheets in a designated file for re-use.
Graded exams should be returned to the instructor after inspection.

3: Calculator Policy: Advanced or graphing calculators and cell phones are NOT allowed on tests. Only BASIC scientific calculators are allowed. These calculators cost about 10 dollars, and do NOT have the following capabilities: Graphing, programming, text storage, wireless connection, symbolic equation solving, differentiating, or integrating. You do need to practice using the calculator EARLY ON and become confident about its operations. Do keep its manual and find the website of the calculator for future reference. The calculators with multi-line mathematical style display can show your steps and reduce data entry error. Casio FX-115ES and Sharp EL-W516 are two calculators below $20 with this ability.
Casio FX-115ES Manual This is easier to search than the printed one.
Casio FX-115ES Appendix Most of the words/buttons here are actually images and therefore not searchable.
Sharp EL-W516 Manual
Remember the text in PDF files is searchable. Look for the binocular icon or press CTRL f.

4: Solution Manual Policy: Students are not to bring solution manuals to class. Copying solutions to homework problems from any source is not allowed. Students should understand their solutions and be able to reproduce it from scratch. Copying final answer from the book, at the end of an incorrect solution, is bad style.

Departmental and University Announcements and Policies:
1: Free Tutoring Lab in LUCAS 209 opens about 10 days after classes start. This is a good place to form study groups, consult with tutors, use computers, etc. My office is nearby at L206. No food or drink or loud conversation or music is allowed in any Lab. Put cell phones on vibration mode and step outside if you have to make a call.

2: University Undergraduate General Catalog.

3: Fall 2010 important dates, final exam schedule, academic calendar, general info

4: Academic Calendar

5: Code of Conduct Handbook and Academic Honesty Policy. . Students should conduct themselves in a manner so that their work will not be questioned.

6: Classes that have less than 10 students by 12th class day are usually cancelled.

Here you can see JAVA applet showing a function and its derivatives. Choose a function from the drop down menu, or type one yourself, for example you can type 5*x^3+20*cos(pi*x)+e^(-2*x), (notice that we use ^ for power and * for multiplication, the software understands pi and e), set boundaries for the picture and drag the horizontal slider. Try to guess what the graph is going to do and then verify it.

Begin reviewing Trigonometry. Many of you have very little background in trig. But this is a topic that needs quite a bit of practice. On one hand you need to keep up with the course and on the other hand you need to spend time and make sure you understand what these trig functions represent. You need this information in Calculus II and then in Differential equations 3301 and then in circuit analysis etc. So plan in advance.

Calculus Video Lecture 14. The Chain Rule Composition of functions, the chain rule formula, examples, geometric explanation, and an indication of the simplified proof.

Correction: One item missing from this lecture is the derivative of a^x.
Here is the formula: (a^x)'= a^x ln a. (See Page 222 Edition 5/Page 201 Edition 6)
Here is the proof:
1) You can use chain rule to show [e^(bx)] ' = b e^(bx).
2) From properties of logarithm we know
a= e^(ln a) hence a^x=e^(x ln a).
3) Now differentiate both sides
(a^x)'= [e^(x ln a)]' = e^(x ln a) ln a = a^x ln a.

Book edition 6 ET, Section 3.4, Page 197-207.
I recommend you do 1-46, 50. Those of you who have had calculus before try 58. The important issue is that you need to imptove your speed and accuracy. In most problems you need to see if f'(x) can be simplified and factored. In that case find roots of f'(x)=0.

To experiment with a chain rule applet you can define two functions, such as y=f(x)=3-(x^2)/2 and y=g(x)=sin(x), and see the graphs of f, g and g(f(x)), as well as the tangent lines and their slopes, at a point (x_0, f(x_0)) (the red spot in the left picture), point (f(x_0), g(f(x_0))), on the second picture, and point (x_0,g(f(x_0))), on the third picture. Notice that you can drag the red spot. What does the color-coordination of various line segments mean? How does the third slope relate to the first two?

Here you can see a three dimensional Java applet of chain rule. Check both Normal Mode and Delta Mode buttons. You can modify angle of view by pressing up/down/left/right buttons, and move on curves by pressing x+ and x- buttons. Can you decipher the picture?

This section is very interesting and challenging. If you were asking why we are learning all these math formulas you get a partial answer in this section. Do read the text and spend time with the problems done in the text. Also expect a rough road and prolonged delays before you get the hang of it. If you want mathematics to be a major part of your career then you must do well in this section. We will have three sections in calculus I that are like this: related rates, graphing, and optimization.

Calculus Video Lecture 22. Related rates. Study of problems from geometry, physics, and engineering where several quantities are related to each other and we use information about their current values and current rates of change to find a missing rate of change. Solutions of three problems are presented. Read the text for introductory problems and basic advice on how to get started.

After you view several problems check to see how the following steps were carried out and try to apply the same general approach.
1) Make a listing of variables whose rates of change are given or requested.
2) Draw a clear picture, if applicable.
3) Give variables names (x,y,v,..) and show them on the picture.
4) Write the rates of change of variables and their current values in a table.
5) Discover the relationship between the variables. This is the hard part; it may need geometry, visualization, or basic science etc. Review geometry formulas under the front cover.
6) Differentiate this relationship with respect to time carefully. (For example remember (x^3)' is not 3x^2, it is 3x^2 x’!).
7) Substitute the values you know to find the one you do not know. The current values of variables do not get to be used until this final stage.

Book Edition 5ET, Section 3.10, Page 256-262.
Book Edition 6ET, Section 3.9, Page 241-247.
Redo all problems that are done in the text and in the video.

Calculus Video Lecture 23. Linearization and Differentials. Linear Approximation, tangent line approximation, Linearization, small angle approximation, differentials, relative error, percentage error. Solution of several sample problems.

Book Edition 5 ET, Section 3.11, Page 262-269.
Book Edition 6 ET, Section 3.10, Page 247-253.

Here you can see a java applet for linear approximation. You can choose or type a function f(x), in place of x^2, choose the base of operation, a, and the displacement, h, as in f(a+h) =approximately equals= f(a)+h f '(a). The horizontal slider changes h, the vertical slider changes the slope of the line. The blue inset is the picture of the error of approximating the graph by the line you have chosen, so if your line is y=mx+b the error function is y=f(x)-(mx+b).

Calculus Video Lecture 24. Maximum and Minimum Points. Definition of absolute or global maximum or minimum, relative or local max or min, extremum points, critical points, The Extremum Value Theorem, Fermat's Theorem, The Closed Interval Method. Solution of problems 47, 53, 56.

OPTIONAL Calculus Video Lecture 33. Newton's Method.
Newton-Raphson Method for finding roots of equations, approximate methods, graphical explanation, algorithm, example, pathological cases.
Corrections: A statement made at the beginning of this lecture says there are no formulas for roots of polynomials of degree four and above. The correct description is: There are no formulas (similar to the quadratic formula) for equations of degree five and above.

An important issue here is the efficient use of a calculator. Make sure you know how to use your own calculator for storing a number and recalling it and grouping expressions in parentheses. There are keys for these activities but each calculator has a different style. On some calculators these are called STO, RCL, and (, ).
For example let x=0.123456789. Find (x+x^2)*sin(x+x^3), but enter x ONLY ONCE.

Applet shows the successive steps of Newton's Method. Click somewhere on the X-axis.

Extra Extra: For your eyes only!.
Basin of Newton's Method. A polynomial has as many roots as its highest power. Depending on where you start Newton's method you will generally converge to one of the roots. This applet colors starting points according to which root they lead to. The whole operation is done on the complex plane (z = x + i y), and creates amazing pictures. Highly recommended for a rainy day. Some non-interactive low-resolution sample pictures are here. But it is better if you create your own and zoom on it, as that is done here. To zoom simply left-click and drag the mouse over the diagonal of the rectangular region you want to enlarge.

You can find more about Newton fractals here.
Here is the resulting fractal image for f(z)=z^3-1.

Here is a basic version of fractal image for f(z)=z^3-1 each color represents set of points which will lead to the same root.
