Question

the period of the function f(z)=tan z is​

Answer 1

Given :  f(z)=tan z

To Find  : Period

Solution:

Period of a function is the interval at which  function returning to the same value.

if p is the period of a function f(x)

=> f(x + p) = f(x)

Period of  tanx  is  π

Period of tan ( ax)    =   π/a

Tan ax = Tan(a(x + π/a)  = Tan(ax + π)  = Tan ax

hence period of tan z  = π
