Trigonometric cofunction identities
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. WebThe value of a trig function of an angle equals the value of the cofunction of the complement of the angle. Cofunction Identities, radians. Cofunction Identities, degrees. sin (90° – x) = cos x. cos (90° – x) = sin x. tan (90° – x) = cot x. cot (90° – x) = tan x.
