- sine or
coversine (in Latin,
cosinus versus or coversinus),
abbreviated coversin, covers, cosiv, or cvs The
coversed cosine or covercosine, abbreviated...
- = 2 sin2(θ/2)) (which
appeared in the
earliest tables), the
coversine (
coversin(θ) = 1 − sin(θ) = versin(π/2 − θ)), the
haversine (haversin(θ) = 1/2versin(θ)...
