Trigonometric identities

When working with trigonometric identities, it may be useful to keep the following tips in mind: Draw a picture illustrating the problem if it involves only the basic trigonometric functions. If the problem expresses an identity between trigonometric functions, try working on one side of the identity to write the trigonometric functions from one side in terms of trigonometric functions on the 2014-10-15 Elementary trigonometric identities Definitions. Trigonometric functions specify the relationships between side lengths and interior angles of a right triangle. For example, the sine of angle θ is defined as being the length of the opposite side divided by the length of the hypotenuse. 1.

These can be "trivially" true, like " x = x " or usefully true, such as the Pythagorean Theorem's " a2 + b2 = c2 " for right triangles. 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. Identity inequalities which are true for every value occurring on both sides of an equation.
