I understand the concept sin(arcsin(x)) = sin(arcsin(x)) which is just x, but now why doesn't sin(3arcsin(1)) = 2arcsin(1) or 2sin(1) . I have been struggling for hours, racking my brain and canceling out many equations tryingto figure out, for my maths homework.

I have an itch to start a commentary channel like Hannah Alonzo and Haylo Hayley. But I don't want to do copycat things like steal from them but find my own stuff (that can be like theirs) through research but have no idea wat ppl would want from a teenage girl perspective. Please do tell me.
