Cos^2 + Sin^2 = 1^2 = 1 StupidLemonEater commented July 25, 2020 Here’s another proof: if you have a right triangle with side lengths a, b, and c (where c is the hypotenuse) then the sine of the angle opposite side a (let’s call it x) is equal to a/c. Likewise the cosine of that angle is equal to b/c.
