Provides the trigonometric functions sin, cos and tan, for use in the graphics and graphicx packages.
Before any trigonometric value is used, it must be pre-calculated, so a usage sequence might be \CalculateSin{22.5} ... \UseSin{22.5}; the argument may also be a LaTeX count, as in \UseTan{\value{mycounter}}, or a count register, as in \CalculateCos{\count@}.
The package is part of the latex-graphics bundle, which is one of the collections in the LaTeX ‘required’ set of packages.
