Symmetry:

Reflection with respect to a line (GeoGebra)
Choose/type the equation of a line
x=0, i.e. yaxis, changing (x,y) to (x,y) in an equation will reflect its graph in the yaxis, mirror or reflection line is x=0
y=0, i.e. xaxis, changing (x,y) to (x,y) in an equation will reflect its graph in the xaxis, mirror or reflection line is y=0
y=x, i.e. 45degree line, changing (x,y) to (y,x) in an equation will reflect its graph in the 45 degree line y=x
y=x, i.e. 45degree line, changing (x,y) to (y,x) in an equation will reflect its graph in the 45 degree line y=x

Reflection with respect to a point (GeoGebra)
changing (x,y) to (x,y) in an equation will reflect its graph in the origin,
this is same as a double reflection, once in xaxis and a second time in yaxis, or a roation of 180 degrees

Reflection in two lines (GeoGebra)
A double reflection is equivalent to a rotation.

Transformations:

Transformations of a function y=cf(ax+b)+d (Desmos)
* The base case is set by a=c=1, b=d=0,
then adjust the paramters/sliders of the app so that it shows the following cases
* Multiple actions have to be done in order specified, except
actions in { } can be done in any order
actions in horizontal and vertical directions can be done in any order.
*If a variable z is replaced by az+b then movements in direction of z axis are according to (zb)/a or z/ab/a.
That is move by b and the scale by 1/a , or scale by 1/a and then move by b/a.
Alternatively you may have individual rules as listed below:
Single Action
 y=f(x)+3, up by 3
 y=f(x)3, down by 3
 y=3f(x), 3 times taller
 y=(1/3)f(x), 3 times shorter
 y=f(x+3), left by 3
 y=f(x3), right by 3
 y=f(3x), 3 times faster or 3 times narrower
 y=f(x/3), 3 times slower or 3 times wider
 y=f(x), reflect left/right, in yaxis
 y=f(x), reflect up/down, in xaxis
Multiple Actions
 y=f(x), reflect in origin, or {reflect in xaxis, reflect in yaxis}
 y=3f(x), {3 times taller, reflect in xaxis}
 y=f(3x), {3 times narrower, reflect in yaxis}
 y=f(2x+3), left by 3, then 2 times narrower
 y=f(2x+3), 2 times narrower then left by 3/2
 y=f(2x+3), {reflect in yaxis, shrink horizontally by half}, move right by 3/2
 y=f(2x+3), move left by 3, {reflect in yaxis, shrink horizontally by half}
 y=2f(x)+3, up by 3/2, then 2 times taller
 y=2f(x)+3, 2 times taller then up by 3
 y=2f(x)+3, down by 3/2, then {2 times taller, reflect in xaxis}
 y=2f(x)+3, {2 times taller, reflect in xaxis}, then up by 3

At above page, bottom left, you see several options,
(1) "MATLAB Online" which allows you to program in web without downloading, and
(2) "Download MATLAB" which allows you to download.
IT says use a WIRED connection at home to perform this task, however I have done it on WiFi and downloaded overnight.
This takes several hours as it is a very large download, so do it at home, and on a good connection!
More details are available at Installation Guide.
MatLab also provides you with its own cloud storage site.
So you either need to install Matlab to your own laptop or connect to cloud version of MatLab or use a Lamar lab which has MatLab,
most engineering and CS labs do, so does GB 113.

TeX
Students who are in senior level classes or above are expected to type their homework and papers.
WORD or Matlab Publisher are two common choices.
Students who are in MS program or contemplating entering one, and more so those who wish to get a PhD, should learn TeX.
Expect to spend as much time as a course for learning TeX. So you want to start early and gradually improve your skill.
Here are some resources among many:

Usage Hints for Desmos

Piecewisedefined and Step functions
Example: In Desmos type y(x)= { 2< x< 0 : x+2, 0< x < 2 : 2x}
Syntax: y={ simple inequality 1 : formula 1 , simple inequality 2 : formula 2 , simple inequality 3 : formula 3 }
Note the usage of braces, colons, and commas.
To define the unit step function use
u(t)= { t < 0 : 0 , t > 0 :1}
Then instead of u_c(t) use u(tc)
Here is an example showing how to enter lengthy functions
The step function: u(t)= { t < 0 : 0 , t > 0 :1}
Function 1: f(t)= t/(1+t^2)
Function 2: g(t)= 7sin(3t)
Function 3: h(t)= 5cos(2t)
A combination of above with various delays:
y(t)=f(t)+u(t3)*g(t3)+u(t5)*h(t5)
Here is an extended example: modeling the solution of a wave equation

Numbers of digits of accuracy
Desmos, by default, provides 3 digits.
In order to get five digits when solving f(x)=g(x) follow these steps.

Graph y=f(x) and then y=g(x) on the same screen. Find the point of intersection and record it.

Graph y=f(x/100) and g=(x/100) (simply replace x by x/100 on existing screen).

Use the wrench icon to modify the x window. For example if in step (a) the root of interest was 2.1 now make sure the window includes 210=2.1*100.
There is an inequality like 10 < x < 10 when you click on the wrench, change it to 205 < x < 215, play with window or the zoom to clearly see the intersection.
Now Desmos shows the root to 5 digits. Record this root and divide it by 100.

Summing up to term N. An example of a "slider"
To plot y = sum of sin (n pi x) / n^2 for N terms type the following

y= sum

A capital sigma shows up with a lower and an upper limit.

In the lower limit you enter the starting value of n, probably 1.

In the upper limit you can enter N, to indicate that you want to add up N terms.

Then you enter your formula , in terms of x and n, e.g. sin (n pi x) / n^2

A slider shows up labeled as N. You can move it over the indicated range.

As default, the range is 10 < N < 10. You can click on "10" or "10" to change the limits and the increment, for example to 1 and 30.

Labeling
Type a coordinate (a,b), a menu comes up, you can also put TeX commands in a back quote as in
`y=\cos x`
How to put Labels

Animation
You can use a slider for parameters. When you use a slider for a time variable you can make an animation.
For a comet effect use a format as
(cos(2t),sin(3t) {t < a} )
(cos(2a),sin(3a))
Access Code
Most introductory courses require an access code. This provides
homework sets, instant checking of answers, and may come with
additional resources such as ebook and instructional videos. Access
codes are for a limited time use by one person during one
semester (unless the course is designated as a multisemester course,
such as Calculus I,II,III, in this case the access code is for three semesters). Once an access code is registered for a course it cannot be used for another person even if it was not used.
Sometimes an unregistered access code can be used for a course other than the one you bought it for. Ot it can be bought from third party sites. If you have an access code or want to buy one and want to make
sure it applies to a text check the following site page for WebAssign Prefix list.
Direct online purchase from the publishing company of WebAssign is the safest and gives most user support but costs more.
There is a twoweek trial period for the code (if purchased directly from WebAssign), and after purchase you have two weeks to get a refund if you drop a course.
Therefore there is no excuse not to get started with homework right away at the start of semester.
Cengage, the publisher of WebAssign, has a
Cengage Unlimited Subscription Plan (CUSP).
In short you pay $120 per semester, or $180 per year, or $240 per two years, and you get Cengage digital textbook library, digital online homework system (WebAssign, MindTap, ...), printed text rental at $8/semester.
To see if it makes sense for you to use a subscription
check here.
Only books published by Cengage are included in the rental agreement. However WebAssign usually includes the ebook.
Starting with 2019 we will adopt Larson, Calculus Early Transcendental, 7th edition, which will be in CUSP and in the rental plan. Also Poole's Introduction to Linear Algebra is a Cengage book and in the rental plan.

WebAssign Hints and Errors
Do a browser check first before attempting your assignment.
On university computers Internet Explorer has more uptodate components than Chrome.
WebAssign errors are rare but occasionally they do occur. If you see one let me know.
More often than not it is the student who has not paid attention to syntax issues or has a typo.
Note that webassign like most computer programs is case sensitive, so B and b are different.
Not only that, font matters too so B is also differnt from B and b. And if that was not enough, you also have β (Greek beta).
It is good to be familiar with Greek Letters.
Also read How to enter exponents, subscripts, roots, functions, etc
And how to use CalcPad to enter formulas
Please pay attention to the following and most of your problems will go away!
Do not mix up:
Exact vs decimal answers, (if it does not tell you to give the answer to say 2 or 3 or 4 decimal places then it wants the exact answer, e.g. cos^{1} (2/
√ 13
) vs 56.3099 degrees )
angles in radians vs angles in degrees (degree angles have a little circle as superscript)
Ordinary font e.g. F for scalars vs bold fonts e.g. F for vectors
Here are some characters you might have difficulty with:
a, A, A, α (alpha)
b, B, B, β (beta)
d, D, D, δ, Δ (delta)
t, T, T, τ (tau)
w, ω (doubleu and omega)
1,l (one and ell)
0,o (zero and oh)
,' comma vs prime (especially after a fraction a comma is common, not to be confused with derivative of denominator)
*,(blank) (missing a multiplication sign or using a blank space in its place in a formula, xy is not understood as x*y)
[],(),{},<> (different fences or delimiters, each book may have a different style)
[] , [[]] (do not double bracket or put a bracket in a bracket)
Keep a record of typical errors in your notebook to remind yourself.

Javabased applets error messages
Many Internetbased mathematical demos used to use Java. However due to security concerns you have to take certain extra steps to be able to use them.
The accepted practice is to move away from such software.
However if you attempt to use them it is very likely that you get one of the following error messages if and when you try to access Javabased apps:
A) Java applications are blocked by your security settings.
B) Missing ApplicationName manifest attribute.
C) Missing required Permissions manifest attribute in main jar.
You need to upgrade JAVA frequently, and remove your older versions,
then close and open your browser,
then include the trusted math site in your
Java seucity exemptions file,
then give permission to your browser to run the app.

0) you did not specify your preferred email address correctly during registration (most common mistake)
1) you typed your email incorrectly during registration
2) you entered a parent's email for yourself during registration
3) you changed your email

You should turn on ALL notifications from any homework software (WebAssign/Aleks/etc) we use. You should not opt out of notifications.
You should also register with your email on WebAssign (if required) and accept to be notified when and if there is new homework.
If you are concerened with privacy issues you can use lamar.edu for school related topics and keep your private email account separate from your lamar email account.
Instructor will not
take any extra actions to reach you after the 12th class day.
"I did not know/I do not get your emails / I do not get WebAssign emails, etc" will not be an acceptable excuse if majority of class knew! Attend classes and check email and webassign daily.

Calculators
You are allowed to have a basic scientific calculator on any test. These calculators typically cost about $15 new.
They do not have graphing or computer algebra or wireless capabilities.
The ones with "natural textbook display" are easier to use. They show formulas similar to how they are printed in texts.
Examples are
Texas Instrument TI30XS or TI030X IIS or TI36X Pro,
Sharp ELW516BSL556 or ELW516XBSL,
Casio FX991EX or FX115ES ,
Cannon F792SGA.
Here is how
natural textbook display looks like.
Note:
You are not allowed to have a phone calculator.
You are not allowed to share a calculator.
You are not allowed to use an advanced graphing calculators (as in TI84 etc).
Appeals and Student Data
In case you want your exam to be reviewed and regraded you need to notify me within one week from the day grades are given.
Two weeks after the final exam your course grade data will be discarded, unless you make a written request in person during the semester.
All issues that may influence your grade should be documented in an email from you to me and acknowledged in an email from me to you.
At the time of the final test, and before final grades are given, send a summary email.
Late Homework
Late homework, if accepted, has a penalty that starts at %20 and increases with the length of delay.
Homework from beginning of semester loses much of its value by the end of semester.
Here is how the late penalty will accrue: [20+3*(xy)] percent, here x is the current homework number and y is the homework number you want to do late.
So if we are doing homework 16 and you want to redo homework 2 the late penalty is 20+3*(162)=62%.
You may be asked to come to my office and show your handwritten solutions of such late homeworks and explain them.
All homework is to be done BEFORE the final. Deadline Extensions, do not have any validity past the day of final.
Students are reminded that waiting for end of semester to see what minimum work is needed to get a particular passing grade is not an acceptable conduct.
Privacy
Please read the login prompt before you log to university network. It states that you should not expect any privacy.
All activity on a computer during class or exam time can be inspected and analyzed by the instructor.
If you use a homework software all activity on it is visible to the instructor and certain employees of the company.
There may be a seating assignment in class.
Your notebooks, papers, calculators, phones and anything visible to instructor may be inspected by the instructor during tests.
Put all private items in your backpack and keep it closed during tests.
You may be asked to change your seat during a test.
If you violate the Test Code or class decorum rules you may get a public reminder in class.
Course Evaluations
The university will send you a notification toward the end of semester to evaluate your courses.
Your input counts, it helps to improve future classes.
Your answers will be private. I do not know who evalauted the course. I get a summary after grades are submitted.
Certain number of points will be added to your last test as a bonus for completing the survey.
If participation rate is over 90% then bonus points will increase substantially.
So encourage your classmates to participate!
Evaluation period will end before the exam period starts.
Go to LUConnect, then Go to Course Evals and complete the survey.
Once done with all evaluations please get a screen shot and also print the acknowledgement page
to prove that you completed the task.
The acknowledgement page may take many forms, for example
this .
This is a page that lists all of your current courses and says you finished evaluating them.
Write your name clearly on the paper you just printed.
Write your course name/section on it. In case you cannot upload the image then give me the actual paper during final.
Upload the screen shot to WebAssign under the assignment "Evaluation".
If you are taking multiple classes from me do the survey and upload one sheet per each class.
Please:
1) Do not print your private answers!
2) Do not give the paper to me earlier or later than final
3) Do not forget to write and circle your name and class name clearly on the paper
If you have technical problems with doing the survey contact Mr. Rossi at
X7143.
Remember: you cannot take the survey after classes end
you need to do it before the finals start!
Sorry, no exception to this rule!!
Neither Mr Rossi nor I can help in that case.
The following categories get a frown instead of a bonus point
"I left it in the car"
"I did not have toner for my printer"
"I could not find a printer on campus that works"
Honor Code
The Golden Rule : You should be able to repoduce, all by yourself, and without any additional help, whatever you write on an assignment or exam or project.
That means I am within my rights to ask you to go to board and redo whatever you wrote.
I am also within my rights to ask you to take a test again.
To avoid misunderstanding during an exam pay attention to the following common sense rules:
Do not look sideways, you are to look at your own papers or screen and protect them from others.
Your face should be visible to the instructor.
No obstruction of face by sunglasses, hair, hand, caps, etc.
No obstruction of ears by musical devices, ear muffs, hoodies.
Bring an official picture ID (Lamar or DL) to all tests.
Use of printed sheets, cell phones, advanced calculators, shared calculators or loose paper is forbidden on tests.
Use of unauthorized websites and communication with others is not acceptable during tests and may result in a grade of F for the course.
All authorized sites will be listed on the exam, any other is unauthorized. Use of homework pages of WebAssign is NOT authorized.
Do not give your WebAssign passwords to any other person for any reason.
Unauthorized logins to WebAssign may result in a grade of F for the course for you.
Fair Use Policy: (or how to get help and not be in trouble with plagiarism rules):
Students are encouraged to try do the homework problems, takehome tests, and projects without seeking help.
But it is OK to consult other students and resources to learn how to solve homework problems or takehome projects or papers.
If you want to seek help on a problem the acceptable process is the following:
(a) Throw away whatever you have written on that problem so far.
(b) Consult with as many resources as you wish, make sure you understand what you read or hear or see.
(c) Write the solution of the problem all by yourself without listening to or looking at any other source. Your new writing must be from scratch and from the beginning.
(d) If you get stuck again go back to step (a).
At the end you should be able to reproduce and justify the steps of the solution you submit. For example by coming to the board and explaining it.
See the penalty schedule for cost of infractions. University Academic Honesty rules apply.
Student Resume
Students are to prepare a onepage resume specific to this course. Please convert it to PDF format.
You will upload it to a WebAssign homework assignment labeled Resume, under "Show My Work".
At the top please put an IDtype photo and add name, email, major, minor, then add details of relevant courses, then add the optinal items.
Resume will detail (where, when) the math courses you have taken, related science courses, major, second/double major/minor, expected date of graduation, jobs, responsibilities, skills.
Any issues I need to be aware of should go on this page at the beginning of semester. You are invited to come and talk to me if you do not feel comfortable writing it.
If you attend two of my classes upload one for each.
Votes, Time Extensions
Occasionally we may have votes in class.
In these cases we go by the vote of students who are present in class.
As a courtesy to all students, and at instructor's discretion, the vote might be conducted via an email. Students will have 24 hours to respond.
Failure to respond indicates the student will accept the vote already cast.
Time Extensions: On some tests you may be given a time extension.
The extensions will be given in increments of 5 minutes. So long as it does not conflict with the next class, and students in attendance do not object.
Absence
For excusable absence from an exam you need a written verifiable proof of emergency.
In case of early contact, and at instructor's discretion, a make up exam might be give.
Please note that for a make up exam several issues cannot be guaranteed: date, time, a quiet room, level of difficulty, etc.
At instructor's discretion, in case of a justifiable absence, an adjusted mix of your other exam grades may substitute the missing grade.
To reduce the negative impact of absence from classes please have a "buddy system" to provide you with missing notes, latest news, coverage report, etc.
Students with excessive unjustified absence may not use office hours for homework help.
Last date of attendance:
For a failing students the instructor has to report the last date of attendance. I will enter the last date at which the student had a passing grade.
Therefore it is important for students who are on probation, due to scholarship, loan, visa, GPA deficiency, etc, or who need to prove attendance for attendance,
to submit all homework and attend all classes.
Sporadic presence in tests or classes will not be considered a proof of attendance.
There is a universitywide audit of attendance near the beinning of the semester.
For census audit your last date of attendance will be the last date at which you had a homework grade of 70% or above.
If you want your physical presence to be counted as attendance then sign a paper with your name and class name and give it to me in each class.
Recommendations
For a strong recommendation letter students need to choose a project, early in the semester, in consultation with the instructor and write a report.
The report need to be nearly finished, well in advance of the recommendation. Interested students need to come and see me with a resume, a transcript, sample of related work, and a list of topics of interest.
ForOfficeUse
If you come across an assignment with a title/name of "ForOfficeUse" ignore it unless you have specific instructions. Any grades or anomalies with respect to such assignments will disappear within a week.
