How do you graph cos x plus pie divided by 4?

Answer 1

amplitude=1

period=2 pi

phase shift=0

vertical translation=pi/4

it will start at (0,1) on the y-axis and cross through pi on the x-axis, then the min will be in the middle of pi and 2 pi at -1. there will be one complete wave to 2 pi on your graph (one curve on top and one on bottom of the x-axis), but then you need to shift it to the left, so that the graph will start at (0,-1).
