Spherical Geometry Let A = ($$\theta_{A}, \psi_{A}$$) be a point on the earth at latitude $$\psi_{A}$$ and longitude $$\theta_{A}$$. Let B = ($$\theta_{B}, \psi_{B}$$) be another point on the earth. Let R be the radius of the earth. Prove that the distance |AB| between A and B is given by $$\cos(\frac{|AB|}{R}) = \sin\psi_{A}\sin\psi_{B} + \cos\psi_{A}\cos\psi_{B}\cos(\theta_{B}-\theta_{A})$$
