The Forgotten 4th Trig. Function | Trigonometry

[@manicmath3557]

There are more torgotten functions. But i feel the chord function along side sine cosine and tangent are MAIN functions. By definition they make complete sides of a triangle. However other functions like secant versine extsecant and other fynctions arent aMain functions to me. Since they arent full lengths if a triangle. But they are still showing the relationships between an angle and length so thetre technucally trig functions. I just see then as pseudo follow ups to the main one

Very cool vid

I think the half versine function is used more so I’d be inclined to say it’s closer to being a “main” function than this one
