If you'd like to do some practice problems to study, check these out--all of this stuff is on your test! (And the answers are in the back of your book). Feel free to stop by tomorrow morning before 7:30 (or C period) if you have any quick questions.

I would also recommend looking at your past quizzes to study!
Here's a list of what's on your test: (textbook section # in parentheses)
- Use a graphing calculator to evaluate trig functions (4.3)
- Ex: sin(2.34) = ?, cos(154 degrees) = ?, sec(2pi/3) = ?, cot(139 degrees) = ?
- SOHCAHTOA "Word Problems" (4.3)
- Draw a triangle to model the scenario
- Use trig ratios to find a missing side length
- Use trig inverses to find missing angle measures
- Know angles of elevation and angles of depression (how to draw them)
- Solve triangles (4.3)
- Use trig ratios and/or trig inverses to find all side lengths and angle measures
- Also, use Pythagorean theorem! And know that angles of a triangle sum (add up to) 180 degrees!
- Define the 6 trig ratios given a triangle (and "theta") (4.3)
- Be sure you know the 6 ratios! Study, study, study!
- Define the (remaining 5) trig ratios given one ratio (4.3)
- Example: Given sin(x) = 3/5, draw a triangle, choose/identify an angle theta, find the third side of the triangle (Pythag.), and then define the remaining 5 ratios!
- Convert angle measures to radians (4.1)
- Convert angle measures to degrees (4.1)
- Find complements and supplements in degrees (4.1)
- Find coterminal angles (+/-) in degrees (4.1)
- Find complements and supplements in radians (4.1)
- Use common denominators/fractions to solve--no converting to degrees!
- Find coterminal angles (+/-) in radians (4.1)
- Sketch angles in standard position (radians and degrees) (4.1)
- Find the measure of a reference angle
- Remember, reference angles are formed by the terminal side of an angle and the X axis!
