Best ResponseYou've already chosen the best response.1the 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

Best ResponseYou've already chosen the best response.0amp=3 period 2pi/3 phase shift= 3pi/2 that right? @etemplin

Best ResponseYou've already chosen the best response.1yes, except phase shift should be either negative or specified "to the left"

Best ResponseYou've already chosen the best response.0@etemplin so for the function y=3sin(3x/2pi/4)...the amp is 3, period is 3pi/2 and phase shift pi/4?
