the graph of y=tan x - pi/2 compared to the graph y= tan x

Question

moved up or down pi/2 units

or

moved left or right pi/2 units

Answer 1

I'm not sure if you meant for the pi/2 to be inside or outside the function, so I made a video explaining how both of them would affect your tangent graph.

Answer 2

The graph is moved to the right π/2 units.
