| 释义 | > as lemmashaversine formula haversine formula n. a formula involving haversines which allows the shortest distance between two points on the surface of a sphere to be calculated using the longitude and latitude of each point.For two points on a sphere of radius r and having latitudes λ1, λ2 and longitudes ϕ1, ϕ2, the distance d between them is given by d = 2r arcsin (√h), where h = haversin (ϕ2 − ϕ1) + cos ϕ1 cos ϕ2 haversin (λ2 − λ1). ΚΠ 1908 Math. Gaz. 4 269 The final reading for the angle A found by calculation above to illustrate the haversine formula to be 65°9′ coming out 65°30′. 1943 National Math. Mag. 17 327 In the first of the chapter the haversine formula is applied to the terrestrial triangle case of two sides and the included angle. 2009 Taxon 58 536/2 Geographic distances between populations were calculated using the ‘Haversine’ formula. < as lemmas |
