Law of cosines with only angles

WebThe role played by acos in the naive law-of-cosines formula is to convert an angle to a distance. That role is played by atan2 in the haversine formula. The tangent of a small angle x is approximately equal to x itself. Consequently the inverse tangent of a number, being approximately that number, is computed essentially with no loss in precision.
