What is the fundamental period of `f(x) = (sin x+ sin 3x)/(cos x+ cos 3x)`

Find the fundamental period of f(x)=cos x cos2x cos3x

Find the period of the function f(x) = (sin x + sin 3x)/(cos x + cos 3x)

what is the fundamental time period of f(x)=cos x.cos2x cos3x

Identify the correct statement the fundamental period of f(x)=cos(sin x)+cos(cos x) is pi

Period of function f(x)=(sin7x+sin3x)/(cos7x+cos3x) is

The period of f(x ) = cos 3x + sin sqrt(3) x is

The period of the function f(x) = (sin x + sin 3x - sin 5x + sin 7x)/(cos x + cos 3x + cos 5x + cos 7x) is

The fundamental period of (|sinx|+|cos x |)/(|sin x - cos x|+|sin x + cos x|) is --

Fundamental period of (sin x)^(@)+(cos x)^(@) is
