## Suggested Algebra and Trig Review

• Study the following sections of Chapter 1 of the textbook. Do the following problems.

### It would serve you well to do more problems than just those listed above.

• Memorize the values of sine, cosine, and tangent for the reference angles 0, pi/6, pi/4, pi/3, and pi/2. Know how to apply these reference angles to find sine, cosine, and tangent values in quadrants I-IV in the coordinate plane.
• At the end of last year in pre-calc you should have received a copy of the "Yellow Book" which reviews basic algebra, geometry, and pre-calculus. You should be comfortable with the content in the yellow book and able to do most of the problems by the end of the summer. You don't have to turn in yellow book problems as homework but you are responsible for understanding the material. If you don't have a copy of the Yellow Book, I've included a link to a PDF below.

The following table summarizes the content of chapter 1 and provides links to online tutorials that may be helpful to you.

### Unit 1.1: Four Ways to Represent a Function

• Understanding the interplay between the four ways of representing a function (verbally, numerically, visually, algebraically).
• Finding the domain and range of a function, regardless of representation.
• Investigating even and odd functions.
• Working with piecewise defined functions.

### Unit 1.2: Mathematical Models - A Catalog of Essential Functions

• The modeling process: developing, analyzing, and interpreting a mathematical model.
• Classes of functions: linear, power, rational, algebraic, trigonometric, exponential and transcendental functions. Include the special characteristics of each class of functions.

### Unit 1.3: New Functions from Old Functions

• The mechanics and geometry of transforming functions.
• The mechanics and geometry of adding, subtracting, multiplying, and dividing functions.
• The mechanics and geometry of composing functions.

Composing Functions

Function Inverses

Piecewise Functions

Shifting and Reflecting Functions

Properties and Features of Functions

Comparing and Interpreting Functions
