On a separate set of axes from 0 to 2π ,

a. Sketch the graphs of the following trigonometric functions:

b. Give the period, amplitude and frequency of each function.

1. y = 3sin 2x

2. y = 2cos 2x

3. y = tan (x − )

4. y = 0.5cos 3x

5. y = –2cos 2x

6. y = 3tan x + 1

7. y = sin2(x − π)

8. y = 2 cos (3x − )

9. y = 4cos(0.5x)

10. y = sin3(x +)
