Trigonometric identities are equalities involving trigonometric functions. An example of a trigonometric identity is. \sin^2 \theta + \cos^2 \theta = 1. sin2 θ+cos2 θ = 1. In order to prove trigonometric identities, we generally use other known identities such as Pythagorean identities. tegese tembung mardi
