Graph of y=-%281%2F2%29tan%282x+%2B+pi%2F2%29 (not the best graph, but it gives you an idea of what it looks like)




Remember the general form is y=a%2Atan%28bx%2Bc%29%2Bd where the period is pi%2Fabs%28b%29, and the phase shift is -c%2Fb



So in this case...

the period is pi%2F2, the phase shift is -%28pi%2F2%29%2F2=%28-pi%2F2%29%281%2F2%29=-pi%2F4
