- n. the hacoversed sine
Sorry, no etymologies found.
The hacoversine has a twin which is just the covercosine divided by 2.
Like its cousin the haversine, the hacoversine is mainly useful for doing trig on a sphere when you don't have a calculator handy to square the familiar trig functions.
"That's a hacoversine, buddy." ha ha ha ha ha ha:) (Yes, this horrendous pun is my sole contribution here;)
