1. Find the exact values of the six trigonometric functions if p(3,5) is a point
on the terminal side of B and B is in standard position.
2. If sin ß is positive and cos B = find the exact values of csc ß and tan B.
3. Determine the amplitude, period, phase shift of y =-2cos (2x +), and
the values of (x, y) for the five key points (do not graph).
4. Find the exact value of the following (you must show your work!):
cot (un")
