    Simple Trig Identities

    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.

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