#but tbh I'd rather use exponential rather than cos or sin sorry girls

trigonometry is so funny cuz like sin has all the good stuff :

sin (0) =0 -> iconic we love when stuff equals 0

sin(x) ~ x -> omg so easy to remember and use unlike some other function like cos(x) - 1 ~??? (only near x = 0 but guess what, in physics almost every number is somewhat close to 0)

sin'(x) = PLUS cos(x) -> omg so convenient, i sure hope cos'(x) = +sin(x) so they can be besties without any betrayal😅

sin(x) > 0 -> keep it positive! (as you smash cos the floor!) (only true when we stay on the good side of the circle but what kind of freak goes to the other side??)

but like for some reason, the main character is cos.
