MA 109 50 FA 01 Study Guide for Exam 4

1. Locate angles on a unit circle. (Section 5.1 # 1-4)

2. Translate from radians to degrees and vice versa. (Section 5.3 # 49-74)

3. Use the unit circle to find values of trigonometric functions. (Section 5.2 # 1-18, Section 5.4 # 27-38, Section 5.5 # 11-18)

4. Given the equation of a line the terminal side of an angle lies on, or given a point on the line of the terminal side of an angle, find the values of the trigonometric functions of that angle. (Section 5.4 # 1-16)

5. Given one trigonometric function of an angle, and what quadrant the angle lies in, find the other trigonometric functions of the angle. (Section 5.4 # 17-26, Section 5.5 # 5-10)

6. Given some trigonometric functions of an angle, find trigonometric functions of complementary angles. (Section 5.5 # 47-52)

7. Use right-triangle trigonometry to find sides of triangles, either in word problems or simply on diagrams. (Section 5.5 # 1-4, Section 7.1 all problems)

8. Graph by hand functions of the form Asin(Bx + C) + D (or cosine). Be able to state the period, amplitude, and phase shift. This will constitute a substantial part of the examination, probably involving a succession of functions gradually getting more complicated. (Section 5.2 # 37-42, Section 5.6 # 1-36)
