Use the fundamental identities to simplify the expression:
cot beta sec beta
I used 1+tan^2u=secu since cot is the inverse of tan. I flipped the tangent, then so it was 1+ (1/tan). But the book's answer is the cosecant of beta. Where did this come from??

Fundamental identities include:
I will let you take it from here.

Is the right answer 1/sinB?

That's correct, although 1/sin(β) is generally written as csc(β), as your answer indicates.
