Question

Fundamental period of the function $f\left(x\right)={\sin }^{100}x$ is

• A. $\frac{\pi }{2}$
• B. $\pi$
• C. $2\pi$
• D. $\frac{\pi }{4}$

Answer 1

The correct option is B $\pi$

Here, the power of $\sin$ function is even.
Hence, the fundamental period of $f\left(x\right)={\sin }^{100}x$ would be $\pi .$
