You can see the Pythagorean Thereom relationship clearly if you consider the unit circle where the angle is t the opposite side is sin t y the adjacent side is cos t x and A 2 b 2 c 2 Dividing through by c2 gives a2 c2 b2 c2 c2 c2 This can be simplified to a c 2 b c 2 1 a c is Opposite Hypotenuse which is sin b c is Adjacent
