I have this following part of a question: ....... where sin x cannot be 0.

Does that mean in my calculations i can not deal with sin x? or what ? because i don't really understand since i am not dealing with numbers to begin with.

$\displaystyle \sin{x} \ne 0$ is stating a domain restriction for $\displaystyle x$ ... $\displaystyle x \ne k \pi \, , \, k \in \mathbb{Z}$
