See below.

Amplitude:

The tangent function has no definable amplitude. This is because:

as #theta->pi/2color(white)(8888)tantheta->oo# which is undefined.

Period:

period of #tantheta=pi#

period of #tan(theta-pi/2)-2=pi# ( No change in period )

Phases shift:

Subtracting #pi/2# from #theta# causes a shift in the positive/right direction by #pi/2#

Plots:
