Using the unit circle, what are the exact values of (cos(3π/2), sin(3π/2))?

Which of the following best defines the amplitude of y = A sin(Bx + C) + D?

Compute the period of y = sin(4x).

For the function y = sin(2x + π/2), determine the phase shift.

Construct y = A sin(Bx − h) + D for a wave with amplitude 2, midline y = 1, period 2π/3, and first crest at x = π/3.
