Re: Nasty bug in Integrate (version 5.0)


Listing the available documentation is straightforward.  For example, execute
this in a cell:

Options[Trace]
Information[Evaluate[#[[1]]]] & /@ %;

I checked comp.soft-sys.math.mathematica and found that TraceInternal
is undocumented.  This suggests other undocumented Mathematica options
might be discovered by using Options[Built-In-Function-Name].  You
would have to sift through all the Built-Ins to identify all the
undocumented options.

Has anyone in MathGroup found any other undocumented options?
