State the phase shift of y=cos(theta[pi/3]). Then graph the function.
I know that you cannot graph on this site but how do I solve for the phase shift and to graph the phase shift, would I first have to graph the current equation?
Thanks.

when is the angle zero?
ThetaPI/3=0
at Theta=PI/3, the consine function ismax, so the phase shift is PI/3 to the LEFT.
It probably would be a good idea to graph the current equation to get the hang of it.

What is the phase shift of y = –csc(3x − ð)?
