If you mean that you would like to see the steps that Mathematica took in evaluating some complicated integral, the answer is no. And you probably wouldn't want to see the steps anyway because it would be a little like watching sausage getting made. If you want to use Mathematica to see and illustrate integration techniques, such as might be taught in a college course, the answer is yes. But you will have to write rules that perform manipulations and perhaps put integrals and other expressions in a HoldForm. Mathematica evaluates many things automatically and sometimes for teaching or learning purposes one wants to stop this. The ExpressionManipulation package and the associated EvaluationTutorial at my web site has routines and examples of doing this with step by step manipulations and derivations. Mathematica really is very good at symbolic manipulations. But it does not have, built-in, all the various routines you might wish. If you are willing to write the routines that you need, usually simple and rule based, you can easily build up the tools you need to perform and teach mathematical theory in any specific area. It is very worthwhile because you not only learn the math, but also Mathematica and you end up with useful tools to boot. You should very seldom have to do things with pencil and paper or via word processing.

I was just wondering if there was a way to display the math in getting the answer to a problem. I'm hoping to understand integrals a bit better and I think this would help. Thanks guys.
