Prove the identity. cos? e csc e + sin(-O) = sin e We will prove the identity by transforming the left side of the equation into the right side. We begin by writing the left side in terms of sines and cosines, and then writing each trigonometric term with a positive 0. We can then combine the terms as a single fraction, and use the Pythagorean Identity to simplify. 1 csc e + sin(-0) = + sin(-0) - sin e sin e cos? e sin e
