See explanation Consider a right angled triangle with an internal angle theta: Then: sin theta = a/c cos theta = b/c So: sin^2 theta + cos^2 theta = a^2/c^2+b^2/c^2 = (a^2+b^2)/c^2 By Pythagoras a^2+b^2 = c^2, so (a^2+b^2)/c^2 = 1 So given Pythagoras, that proves the identity for theta in (0, pi/2) For angles outside that range we can use: sin (theta + pi) = -sin (theta) cos (theta + pi
