Question

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

• A. $\pi$
• B. $2\pi$
• C. $\sqrt{\pi }$
• D. None of these

Answer 1

The correct option is D None of these

$f\left(x\right)=\sin \sqrt{x}$
Domain of $f\left(x\right)$ is $x\ge 0$, domain is not equal to $R$, So $f\left(x\right)$
is not a periodic function
