### Class Summary and Handouts

Class 17: Trig Identities II and Graphing Trig I
Today we introduced the graphs of $$\sin(x)$$ and $$\cos(x)$$. To get a good gut feeling for graph translations for sine and cosine, try playing around with this interactive graphic.

Class 16: Trig Identities - Part I
We introduced most of the important trigonometric formulas. We used the trigonometric identities in two ways: to compute things like sin(pi/12) and to "verify" trigonmetric identities. You can find a handout summarizing our trig formulas here.

Class 3: Function Notation
Today we talked about "function notation" from two perspectives: algebraic and graphical. To get a good gut feeling for the graphical side of things, try playing around with this interactive graphic.

Class 2: Intervals, Inequalities, and Introducing Functions

Class 1: Algebra Review
Today, we reviewed the algebraic tools that we will use the rest of the course. Some particularly important rules were summarized in the Algebra Review Handout

## Textbook Information:

Book: Precalculus (UConn edition) by Carl Stitz and Jeffery Zeager
There are three ways to obtain a copy of the textbook

• Everyone should download a free PDF copy here.
• You can buy a print copy from the bookstore.
• You can buy a print copy online. (Pay attention to printing and shipping times if you are buying a copy online).
I recommend buying a paper copy. You can take notes, draw sketches, and compare several pages more easily.

Online Homework: You can access the online homework system at https://webwork.mathlogic.org/webwork2

Recommended Browser: Mozilla Firefox

Note: When you first access WeBWorK, you will get a warning.

• This is because the WeBWorK server is not recognized by a trusted "certificate authority".
• In Firefox, the warning looks like this (click to enlarge):
• Read the warnings carefully, and add an exception.

As an experiment to bring down book costs, I am experimenting with a free system. If there are technical difficulties, you will need to purchase a \$30 access code for a commercial system.
