What is the period of the function \(\tan 4x\)?

Answer and explanation

Correct answer: \(\dfrac{\pi}{4}\)

The governing rule is that the fundamental period of \(\tan(kx)\) is \(\pi/|k|\), because tangent repeats after an argument increase of \(\pi\). For \(f(x)=\tan 4x\), require \(4(x+T)=4x+\pi\). Subtracting \(4x\) gives \(4T=\pi\), hence \(T=\pi/4\). Therefore, option D is correct. The factor 4 compresses the ordinary tangent graph horizontally by four, changing its period from \(\pi\) to one-fourth of that value. Option A is the period of \(\tan x\) without the coefficient; options B and C result from incorrect division and do not reproduce the function for every x.
