Hello Netters,

I'm looking for a program to find and simplifies deratives of a
function. For example:

! % derive(+Function,+DerVariable,+Derative)
! %
!
! ?- derive(a*x + b*x^2, x, Answer).
!
! Answer = a + 2*b*x

I've looked at the archive, but couldn't find the thing I needed:
src.doc.ic.ac.uk:/computing/programming/languages/prolog/pd-software

Thanks for your help!

-- Fred
