I need solutions for calculus help

Question

The answers are fill in the blank

Verify the identity.

cos^2(v)/sin(v) = csc(v) - sin(v)

Begin by rewriting the given expression in terms of sine only. Then, simplify.

cos^2(v)/sin(v) = /sin(v) answer a

= (1/ ) - sin(v) answer b

= answer c

Answer 1

cos² v = 1 - sin² v

Convert numerator and divide.
