As an aside, I just realized the relationship between #trigonometry and the Pythagorean theorem: “1 = cos(t)^2 + sin(t)^2” - now it all makes sense ! Why didn’t it enter my thick skull when I was in high school is anyone’s guess - maybe it was never introduced to me that way... Or maybe I was asleep because I couldn’t see the point - I guess I should have introduced myself to radio sooner !
