# Exam 2 Review Problems

First, make sure you can do all the problems from:

In addition, be able to do the following problems:

1. Find $\mathrm{sin}(\theta)$ if $\mathrm{cos}(\theta) = -1$.
2. Find $\mathrm{csc}(\theta)$ if $\mathrm{tan}(\theta) = 1$ and a point on the terminal side of $\theta$ lands in Quandrant III.
3. Find exact values of sin, cos, tan, sec, csc, and cot of the following angles:
• $90^\circ$
• $120^\circ$
• $135^\circ$
• $150^\circ$
• $180^\circ$
• $210^\circ$
• $225^\circ$
• $270^\circ$
• $330^\circ$
• $750^\circ$
4. Given the following angles, draw them in standard position, plot a point on their terminal sides and find sin, cos, and tan:
• $240^\circ$
• $150^\circ$
5. If the following points are on the terminal side of an angle $\theta$ drawn in standard position, draw the angles and find the values of sin, cos, tan, sec, csc, and cot:
• P = (-1, -2)
• P = (2, 1)
• P = (-3, 4)
• P = (5, -13)
