Question

$sin\left(0\right)=sin\left(\pi \right)$ => sine function is periodic with period $\pi$

• A. True
• B. False

Answer 1

The correct option is B

False

For a function to be periodic with period p,

f(x+p) must be equal to f(x) for all x in domain.

But $sin(\pi +x)$ is not always equal to sin(x). So $\pi$ is not a the period for sine function
