. We describe locations on the Earth using latitude and

. We describe locations on the Earth using latitude and longitude 0. Using these coordinates, we describe a location A on the Earth with A = (A,A). Las Vegas, for example, has coordinates (36° N, 115° W), or (36°, -115°). Prove the distance formula cos(AB/R) = sin A sin o+cos A COSOB COS(OA - 0B), where R is the radius of the Earth. Hint: Look at AABN where N is the North pole.
