    Let a function be f(x), T is it's period if \[f(x+T)=f(x)\] it'll also hold for integral multiples of T \[f(x+nT)=f(x)\] n=1, 2, 3,4, 0, -1, -2

    If you look at the graph of tan x, it's period is \(2\pi\)

    Now if we have tan 2x, it's period will be \(\frac{2\pi}{2}\) can you tell me, what will be the period of tan 4x ?

    The period of tan 2x is 2(pi)/2? or 2x/2? It's hard to read it on my computer
