Apparently I didn't get my
question across.

OK. I know this:

\!\(\(\nD[{x*z + y*z\^2 - x}, {x, 1}]\)\)

Yields this:

{-1+z}

Which is:

\!\(\[PartialD]\/\[PartialD]x\)

Which is nice, unfortunatly that is NOT what I want!

I want \!\(\[PartialD]z\/\[PartialD]x\)

Which I know to be:

\!\(\(\(-1\) + z\)\/\(x + 2\ y\ z\)\)

Because I just did it by hand.

So now I'm confused, can I use this
expensive software to do my work or
is this #2 pencil I'm holding a better
choice??

Regards,
->C
