The Trigonometric Identities are equations that are true for Right Angled Triangles. (If it is not a Right Angled Triangle go to the Triangle Identities page.) Each side of a right triangle has a name: Adjacent is always next to the angle

Trigonometric Identities Tutor is an app available for the apple iOS app store that will help you memorize the trigonometric identities most commonly used for 

We start with powers of sine and cosine. EXAMPLE 1 Evaluate . SOLUTION Simply substituting isn’t helpful, since then . In order to integrate powers of cosine, we would need an extra factor. Similarly, a power of

Similarly, an equation which involves trigonometric ratios of an angle represents a The main trigonometric identities between trigonometric functions are proved, using mainly the geometry of the right triangle. For greater and negative angles, see Trigonometric functions. Trigonometric identities are equalities involving trigonometric functions. An example of a trigonometric identity is.

De Silva A Trigonometric identity or trig identity is an identity that contains the trigonometric functions sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), or cosecant (csc). Trigonometric identities can use to: Trigonometric Identities List Reciprocal Identities. Pythagorean Identities.
