In this first section, we will work with the fundamental identities: the pythagorean identities, the even odd identities, the reciprocal identities, and the quotient identities. Solution : let a = (1 cos θ) (1 cos θ) (1 cot2θ) = 1 and b = 1. a = (1 cos θ) (1 cos θ) (1 cot2θ) a = (1 cos2θ) (1 cot2θ) since sin2 θ cos2 θ = 1, we have cos2 θ = 1 sin2 θ then, a = sin2θ ⋅ (1 cot2θ) a = sin2θ sin2θ ⋅ cot2θ a = sin2 θ cos2 θ a = 1 a = b (proved) problem 5 : prove : cot θ tan.
