"May as well be circular functions of trig to them"

The good old unit circle! Just about all of trig can be derived from it. For those wondering the unit circle is a circle with a radius of 1 at co-ordinates 0,0 (x,y) on a two dimensional plane.

45 years ago I made A’s in that subject. Never used it after that. Gone from my shrinking brain.

When I think of the math & statistics that I was fluent in (HS & college) that were never touched again and seem like Greek to me now, it’s a little depressing.
