  1. Multiply numerator and demoninator by sin^2. This does not change the value.
    You end up with

    (sin^2 - 1)/cos^2 =
    -cos^2 /cos^2 =
    -1

    No matter what the angle theta is

    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.
