Risch algorithm

Hello T68492!

You have deleted the example of the function, for which Axiom can find an antiderivative, and no other software can, with the claim, that Mathematica can solve this problem. This is incorrect (Mathematica's answer contains non-elementary fuctions), and this was already discussed on the talk page [1]. I think it's important to show, that even the algebraic part of the Risch algorithm is implemented in one software only (Axiom). Note that the algebraic part of the Risch algorithm is the easiest one, but still is very complex. Hope some other authors of other software will read this and implement the algebraic part of the Risch algorithm, or some other mathematitions will find better algorithm (which for algebraic part I expect exists).

I have not changed your edit, decided first to discuss it with you. Do you agree with my arguments?

Thank you and sorry for my bad English. Gaz v pol (talk) 12:28, 26 July 2008 (UTC)[reply]
