Question

Fundamental period of the function $f\left(x\right)={\sin }^{2}x$ is

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

Answer 1

The correct option is A $\pi$

Graph of $f\left(x\right)={\sin }^{2}x$

From the above graph values are being repeated after an interval of $\pi$.
So, fundamental period of $f\left(x\right)={\sin }^{2}x$ is $\pi .$
