Tan

Tan[z] gives the tangent of z.

Mathematical function (see Section A.3.10).

The argument of Tan is assumed to be in radians. (Multiply by Degree to convert from degrees.)

Sin[z]/Cos[z] is automatically converted to Tan[z]. TrigFactorList[expr] does decomposition.

Tan is automatically evaluated when its argument is a simple rational multiple of ; for more complicated rational multiples, FunctionExpand can sometimes be used.

See Section 1.1.3 and Section 3.2.6.
