THE CHINESE UNIVERSITY OF HONG KONG Department of Mathematics MATH4033 Solution for Homework 2 1. (a) X is 1-1: Suppose X (θ 1,ϕ 1) = X (θ 2 2). Since cos is injective on the interval (0,π), so θ 1 = θ 2. Therefore, we have cos ϕ 1 = cos ϕ 2 and sin ϕ 1 = sin ϕ 1, so that ϕ 1 = ϕ 2 Thus, X is injective.
