Use the trigonometric graphs to evaluate the following 1 cos

Use the trigonometric graphs to evaluate the following.

1. cos(pi)

2. sin (3 pi/2)

3. sin(2pi)

4. cos0

5. tan(pi/2)

6. cot(pi/2)

7. sin(pi)

8. cot(3pi/2)

Thank you!

1. cos(pi) = -1

2. sin (3 pi/2) = -1

3. sin(2pi) = 0

4. cos0 = 1

5. tan(pi/2) = Infinite

6. cot(pi/2) = 0

7. sin(pi) = 0

8. cot(3pi/2) = 0
