Trigonometry Identities are equalities that involve trigonometry function.These function involve curtain function of 1or more to anThe distinct of trigonometry identities can involve angle or side length of a triangle. To solve the trigonometry identity function the function need to be first simplified and for the second step the common method is to use the substitution rule and then simplifying the answer. All trigonometry identities function are based on the 6 trigonometry ratio which is sine, cosine, tangent, cosecant, secant and cotangent. All fundamental trigonometry identities is based on the right triangle such as adjacent side, hypothenuse side and opposite side.
