the amplitude of this function is the number in front of cos its always positive its 3 the period is 2pi/(the number with x) 2pi/3 the phase shift is the number after x the function was moved left 3pi/2

@etemplin so for the function y=3sin(3x/2pi/4)...the amp is 3, period is 3pi/2 and phase shift pi/4?
