Important in navigation, it is a special case of a more general formula in spherical trigonometry, the law of haversines, that relates the sides and angles of spherical triangles. The first table of haversines in English was published by James Andrew in 1805, but Florian Cajori credits …

WebMar 23, 2024 · Hello again, Dena. You called my bluff! Good - now I have a reason to write up my derivation of the haversine formula. I had derived the cosine formula for great-circle distance, but not the haversine formula. I was reluctant to send the formula to you without having checked it out, so I derived it before I answered you.
