Subject: RE: Sinus and cosinus functions
From: edx (Felix.Arends_at_gmx.de)
Date: 2002-08-31


Maybe we could implement a sin / cos function into math.h (using only
one table). Otherwise, more memory is used if more than one sin-table is
created. Also, it will be easier for coders to use a pre-written sin
function.
