Hey, It's Leo again; I was hoping I could ask you one more question to help me prep for my upcoming ACTs. Again, if you could show me your answer and the steps you used to get there, I would very much appreciate it.

I am asked to verify the identity of this problem:

[(cos(theta) * cot(theta)) / (csc(theta))] - 1 = -sin^(2)theta

Thank you for your time, Ms. Yang! Am very grateful for the assistance you provide.

Dear Leo,

This solution uses the quotient identities

cotθ = cosθ/sinθ

cscθ = 1/sinθ

then the Pythagorean identity

sinēθ + cosēθ = 1
