Thinking of sine and cosine as ratios of side lengths in a right angled triangle, sin (x) = o/h and cos (x) = a/h, so the sin (x)^2 + cos (x)^2 becomes (o^2 + a^2)/h^2. By Pyhtagoras, o^2 + a^2 = h^2, so we get h^2/h^2 = 1. sin/cos = tan is derived similarly, sin/cos = (o/h)/ (a/h) = o/a = tan ... cumberland valley rheumatology
