Just to make thing clear for everybody, with all different backgrounds in mathematics, why is using the haversine formula proposed earlier the worst possible way to go when one would decide to clear the lunar distance by longhand calculation?
What would be the better way? The sine/cosine formulation? Using logarithmic tables? Why would all other possibilities be better than using the haversine function?
