Is there some kind of constant to height rise per degree from 0 to 90 as a radius of a circle rises.  When I looked at degrees as a percentage of the height rise it didn't work. Kind of trying to figure it all out since the 90 degree height above the chord isn't half the chords length.

Cosine and sine. Learn them. Live them. Love them.

Starting out, consider that 90 degrees is 1/2 Pi radians.

Then, understand that the sine of 1/2 Pi is 1. And the cosine of 1/2 Pi is 0.

Work the trigonometry from there.

Constant? No.

Function? Yes…
Sine and Cosine
