The pythagorean trigonometric identity, also called simply the pythagorean identity, is an identity expressing the pythagorean theorem in terms of trigonometric functions. Equalities (equations) that use trigonometric functions. This is a trig 2 example that shows how to verify identity of a trigonometric equation using the pythagorean trigonometric identities.

There's also one for cotangents and cosecants, but as cotangents and cosecants are rarely needed.

These can be trivially true, like x = x or usefully true, such as the pythagorean theorem's a2 + b2 = c2 for right triangles. Now, if the y coordinate is 5, what does that mean? The pythagorean identities can be used to simplify problems by transforming trigonometric expressions, or writing them in terms of other trigonometric functions. Pythagorean identities are identities in trigonometry that are extensions of the pythagorean theorem.
