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??

**MathMate**, Monday, January 4, 2010 at 9:03pmFundamental identities include:

cot(β)=cos(β)/sin(β)

sec(β)=1/cos(β), and

csc(β)=1/sin(β)

I will let you take it from here.

**MathMate**, Tuesday, January 5, 2010 at 12:02amThat's correct, although 1/sin(β) is generally written as csc(β), as your answer indicates.
