The angle of elevation θ of the sun in the sky at any latitude L is calculated with the formula sinθ=cosDcosLcosω+sinDsinL. ω is the number of radians that the Earth has rotated through since noon when ω=0. D is the declination of the sun. Westville has latitude L=37.9°. Find the angle of elevation θ in degrees of the sun at 3 PM on February 29, 2012, where at that time D≈−0.1425
