The following (particularly the first of the three below) are called "Pythagorean" identities. sin 2 ( t) + cos 2 ( t) = 1. tan 2 ( t) + 1 = sec 2 ( t) 1 + cot 2 ( t) = csc 2 ( t) Advertisement. Note that the three identities above all involve squaring and the number 1. You can see the Pythagorean-Thereom relationship clearly if you consider.

Trigonometric identities are equalities involving trigonometric functions. An example of a trigonometric identity is. \ [\sin^2 \theta + \cos^2 \theta = 1.\] In order to prove trigonometric identities, we generally use other known identities such as Pythagorean identities. Prove that \ ( (1 - \sin x) (1 +\csc x) =\cos x \cot x.\)
