List of trigonometric identities. In mathematics, trigonometric identities. are equalities that involve trigonometric functions and are true for every single value of the occurring variables. Geometrically, these are identities involving certain functions of one or more angles.
Period. The period of a function is the number, T, such that f ( q + T ) = f ( q ) . So, if w is a fixed number and q is any angle we have the following periods. sin ( wq )
Quotient Identities. tan = cos cos. cot = sin.
Range Period. The period of a function is the number, T , such that f ( + T ) = f ( ). So, if ! is a fixed number and is any angle we have the following periods. sin (! ) ! 2 T = ! cos (! ) ! 2 T = ! tan (!
