  11. Hello Netters,
  12.  
  13. I'm looking for a program to find and simplifies deratives of a
  14. function. For example:
  15.  
  16. ! % derive(+Function,+DerVariable,+Derative)
  17. ! %
  18. !
  19. ! ?- derive(a*x + b*x^2, x, Answer).
  20. !
  21. ! Answer = a + 2*b*x
  22.  
  23. I've looked at the archive, but couldn't find the thing I needed:
  24. src.doc.ic.ac.uk:/computing/programming/languages/prolog/pd-software
  25.  
  26. Thanks for your help!
  27.
