1. Find all values of θ that satisfy the equations below. Assume 0 ≤ θ ≤ 2. Use exact values. Homework Help ✎

1. sin θ =

2. cos θ =

3. tan θ =

4. csc θ =

Draw a unit circle. In which quadrants is sine negative?

1. What special angle is this?
2. In which quadrants is cosine positive?

$\tan(\theta)=\frac{\sin(\theta)}{\cos(\theta)}$

$\tan(\theta)=\frac{\sqrt{3}}{1}=\frac{\sqrt{3}/2}{1/2}$

$\frac{1}{\sin(\theta)}=\frac{\sqrt{2}}{1}$
