Primary objective of this article is to Define and Discuss on Tangent Identities. Here explain Tangent Identities in Trigonometry point of view. Formulas with the tangent function can be produced from similar formulas involving the sine and cosine. The preceding three cases verify three formulas referred to as the reduction identities with regard to tangent. These reduction formulas are of help in rewriting tangents of angles which can be larger than 90° because functions of acute perspectives. The double‐angle identity with regard to tangent is obtained by using the sum identity for tangent.
