Quick question guys..(adsbygoogle = window.adsbygoogle || []).push({});

I understand how trig graphs work (cos, sin, tan etc.). What I don't understand is when there is a horizontal translation of say, pi/4, I notice that the graph moves, but I don't really understand how to know exactly how far to move. For example if your HT was pi/4 and your graph was extended on the x axis -2pi -> 2pi, and the original graph crossed once at -2pi, then where would the new point hit when you apply the translation?

Sorry if that was confusing, any help is appreciated!
