Cos

FilledSmallSquareCos[z] gives the cosine of z.

FilledSmallSquare Mathematical function (see Section A.3.10).

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

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

FilledSmallSquare See The Mathematica Book: Section 1.1.3 and Section 3.2.6.
