What I would like as an output of ByParts is this Integrate[f*g,x] == f*Integrate[g,x] - Integrate[D[f,x]*Integrate[g,x],x] where the integration on the left IS NOT performed, the integration of g in the two integrals on the right is performed but the last integral on the right is unevaluated. Put in other words, I would like Mathematica to display the kind of formula the student would get using integration by parts. I have found this surprisingly difficult to do. ----------------------------- I suspect the Calculus Wiz is programmed to do this for you. Read about it at http://store.wolfram.com/view/calcwiz/?36F0EBB0-39EA Even if it doesn't it will likely have lots of features you will find helpful in teaching Calculus. Regards, Ted Ersek
