 \item Two new functions in the \module{math} module,
 \function{degrees(\var{rads})} and \function{radians(\var{degs})},
 convert between radians and degrees.  Other functions in the
-\module{math} module such as
-\function{math.sin()} and \function{math.cos()} have always required
-input values measured in radians.  Also, added an optional \var{base}
-argument to \function{math.log()} to make it easier to compute
-logarithms for bases other than \code{e} and \code{10}.
