- What are the basic trigonometric identities? | Purplemath
In mathematics, an "identity" is an equation which is always true, regardless of the specific value of a given variable An identity can be "trivially" true, such as the equation x = x or an identity can be usefully true, such as the Pythagorean Theorem's a2 + b2 = c2
