Periodic Functions

Prove that the derivative of a periodic function of period T is a periodic function of period T.

If f (x) is periodic function with period T, then the function f (ax+b) where a gt 0, is periodic with period

If f (x) is periodic function with period T, then the function f (ax+b) where a gt 0, is periodic with period

If f(x) is a periodic function of the period k then f(ax+b) is a periodic function of the period_____.

If f(x) is periodic function with period, T, then
