trig – Sim­ple trigono­met­ric func­tions

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 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 ‘re­quired’ set of pack­ages.
