Tan

Usage

• Tan[z] gives the tangent of z.

Notes

• 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.
