Exercise 6.2. Exercise 6.3. (EMBHH) An identity is a mathematical statement that equates one quantity with another. Trigonometric identities allow us to simplify a given expression so that it contains sine and cosine ratios only. This enables us to solve equations and also to prove other identities.Fundamental Identities. If an equation contains one or more variables and is valid for all replacement values of the variables for which both sides of the equation are defined, then the equation is known as an identity. The equation x 2 + 2 x = x ( x + 2), for example, is an identity because it is valid for all replacement values of x.This trigonometry provides plenty of examples and practice problems on cofunction identities.
