Product to sum identity trig
WebbA trigonometric identity that expresses the transformation of sum of the trigonometric functions into the product form of trigonometric functions is called the sum to product identity. In trigonometry, there are two types of sum to product transformation identities and they are used as formulas in mathematics.
