Sin

Usage

Sin[z] gives the sine of z.


Notes

• Mathematical function (see Section A.3.10).
• The argument of Sin is assumed to be in radians. (Multiply by Degree to convert from degrees.)
Sin is automatically evaluated when its argument is a simple rational multiple of  ; for more complicated rational multiples, FunctionExpand can sometimes be used.
• See The Mathematica Book: Section 1.1.3 and Section 3.2.6.
• See also: ArcSin, Csc, TrigToExp, TrigExpand.
