Trigonometric ratios are defined using the proportions of the sides of a right-angled triangle. Each of these ratios has a separate formula. It uses the three sides and three angles of a right-angled triangle. Integration problems regarding the product of a trigonometric ratio , such as cosine, can be solved using the cos a cos b formula. By taking into account the product term, such as cos a cos b, and transforming it into sum, the cos a cos b formula proves to be quite helpful in reducing the trigonometric statement. Standard Identities are a set of algebraic expressions that are used to simplify a mathematical problem. An algebraic equation that holds true irrespective of the value of its variables is called an identity.
