At present Sage punts to Maxima to compute integrals. If I am not mistaken the version of Maxima which is bundled with Sage is a little out of date. I don;t know if the plan is to continue calling Maxima or to compute integrals in some other way. Maxima uses several methods to compute integrals. Definite integrals are, for the most part, handled separately from indefinite. There is an implementation of the Risch method. There has been a lot of terrific work lately (thanks to Dieter Kaiser and Raymond Toy) on integrals of special functions (gamma function and so on). If you would like to join the fun, I suggest that you post a message to the Maxima mailing list about it. See: http://maxima.sourceforge.net/maximalist.html We would be glad to have your help.
