I don't know if there is a "the" equivalentWhat is the equivalent of the following expression sin theta + cos theta cot theta?
where did "beta" come from?I started by finding equivalent for cot theta.
sin theta + cos theta ( sin theta/cos theta)
This gave me sin theta = cos theta sine beta + 1
Just FYI: Sine, cosine, tangent, etc, are functions, so they need arguments. Just as you wouldn't say "ln", because natural log needs to be the log of something, so also you can't say "sin" and "cos" without their arguments. Also, teachers usually count off for this sort of thing as being sloppy and incomplete. So don't drop the arguments!The little mistake you made is that cot is cos/sin and not sin/cos. The final answer is csc.
