# Graphing cosine functions

How would I add increments of p/4 to an x-axis when phase shifting a cosine graph.

Say my x-axis looks like:

0 | | p/2 | | p | | 3p/2 | | 2p

How do I easily fill in the increments (|)?

I am so thoroughly confused and have been trying to understand this for days. If my phase shift is (x-pi/4) : my x axis would look like: 0 | | pi/2 | | What are the values of those first lines after 0?? and the values of the two lines after pi/2??

Since you are translating the graph of y = cosx pi/4 to the right, just add pi/4 to each of 0, pi/2, pi, and 3pi/2 to get pi/4, 3pi/4, 5pi/4, and 7pi/4
