Basic trigonometric identities

sum the total amount resulting from the addition of two or more numbers, amounts, or items sum to product and product to sum formulas tan the ratio of the opposite side to the adjacent side of a particular angle of the right triangle.. The sum-to-product formulas allow us to express sums of sine or cosine as products. These formulas can be derived from the product-to-sum identities. For example, with a few substitutions, we can derive the sum-to-product identity for sine. Let u + v 2 = α and u − v 2 = β.

We can use the product-to-sum formulas, which express products of trigonometric functions as sums. Let’s investigate the cosine identity first and then the sine identity. Expressing Products as Sums for Cosine. We can derive the product-to-sum formula from the sum and difference identities for cosine. If we add the two equations, we get:.
