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.
