WebPythagorean identities are important identities in trigonometry that are derived from the Pythagoras theorem. These identities are used in solving many trigonometric problems where one trigonometric ratio is given and the other ratios are to be found. The fundamental Pythagorean identity gives the relation between sin and cos and it is the most commonly … In other words, the function sine is differentiable at 0, and its derivative is 1. Proof: From the previous inequalities, we have, for small angles , Therefore, ,
