Prove that the following identity is true. cot 0 cos 0 + sin 0 = csc 0 We begin by writing the left side of the equation in terms of sines and cosines. We can then combine the terms as a single fraction, and use a Pythagorean Identity to simplify. cot 0 cos 0 + sin COs sin e = sin 0 + sin 0 cos20 sin 0 X sin 0 = CSC 0
