Question

Does $\sin \left(x\right)$ or $\cos \left(x\right)$ start at $0$?

Answer 1

Explanation for correct option:

If we draw the graph of $\sin \left(x\right)$ and $\cos \left(x\right)$, then we will clearly understand.

Therefore, it is clear that in between $\sin \left(x\right)$ and $\cos \left(x\right)$, $\sin \left(x\right)$ starts at 0.
