Hello friendly helpers and knowledgable personages,
I'm sure this is a problem encountered (and answered) before. And it
is just one of the many I have encountered with this drat perverse
progam. Anyway ...
The following two commands (this is an extremely cut down version of
my problem so try and be general)
Plot[Sin[x]/x, {x, 0, 1}]
Plot3D[y*Sin[x]/x, {x, 0, 1}, {y, 0, 1}]
The first works perfectly, correctly going toward the limit at x=0 of
1.
For the second I get ...
Power::infy : Infinite expression 1/0. encountered.
\[Infinity]::indet : Indeterminate expression 0. ComplexInfinity
encountered.
Plot3D::plnc: y*Sin[x]/x is neither a machine-size real number at
{x,y}={0., 0.} nor a list of a real number and a valid color
directive.
Please explain, Vielin Dank, Mathieu McPhie
