0 + π/4 = π/4, π/2 + π/4 = 3π/4, π+ π/4 = 5π/4, 3π/2 + π/4 = 7π/4

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

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??04/16/21
