I would like to have Mathematica demonstrate the result of integrating expressions like x^n E^(-x) as part of a calculus lesson on integration by parts. Unfortunately, I get Integrate[x^2 E^(-x), x] = -Gamma[3, x] when I would prefer to get Integrate[x^2 E^(-x), x] = (2 + 2x + x^2) E^(-x). Can anyone tell me how to suppress the use of the gamma function for problems like this? Thanks in advance, Robert Beezer University of Puget Sound beezer at ups.edu
