In mathematics, an "identity" is an equation which is always true, regardless of the specific value of a given variable. Need a custom math course? K12 College Test Prep. Logically, mathematical identities are tautologies; that is, they are expressions which restate the same expression in a different way. In other words, the identities allow you to restate a trig expression in a different format, but one which has the exact same value. There are loads of trigonometric identities, but the following are the ones you're most likely to see and use.

Trigonometric Identities are useful whenever trigonometric functions are involved in an expression or an equation. Trigonometric Identities are true for every value of variables occurring on both sides of an equation. Geometrically, these identities involve certain trigonometric functions such as sine, cosine, tangent of one or more angles. Sine, cosine and tangent are the primary trigonometry functions whereas cotangent, secant and cosecant are the other three functions. The trigonometric identities are based on all the six trig functions. Check Trigonometry Formulas to get formulas related to trigonometry.

Given a right angled triangle with sides a , b and c consider the following diagram:. That is, the distance from the origin to any point x,y on the circle is the radius r of the circle. Picture a circle of radius r centred at the origin, and pick a point x,y on the circle:. If we draw a line from that point to the origin, its length is r.
