Polar graphs

If Polar coordinates must have theta between 0 and 2PI (2PI convention) or polar coordinates between -PI and PI (PI-convention) then how are values of theta outside either of these ranges allowed to be inputted into polar graph equations of the form r=f(theta)

0 to 2pi is a circle.

So say if you have 4pi, this is equivalent to 2pi.

You basically convert them into the allowed range.
