These are also known as the angle addition and subtraction theorems (or formulae). The angle difference identities for and can be derived from the angle sum versions by substituting for and using the facts that and . They can also be derived by using a slightly modified version of the figure for the angle sum identities, b…

WebProving Trigonometric Identities - Basic. 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.
