In trigonometry trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined Geometrically these are identities involving certain functions of one or more angles When the height and base side of the right triangle are known we can find out the sine cosine tangent secant cosecant and cotangent values using trigonometric formulas The reciprocal trigonometric identities are also derived by using the trigonometric functions
