Question:

(a) Prove that, for all θ,ϕ,ψ,

is a proper orthogonal matrix.


(b) Write down a formula for Q−1. Remark. It can be shown that every proper orthogonal matrix can be parameterized in this manner; θ,ϕ,ψ are known as the Euler angles, and play an important role in applications in mechanics and geometry.
