The Maxima add-on package abs_integrate can make some progress, but craps out with an error ... load (abs_integrate); foo : integrate (abs (cos (x + y)), x, 0, %pi); => messy expression integrate (foo, y, 0, %pi); => divide by 0 error This is with Maxima 5.23. I didn't check whether the first result is correct. If anyone is interested, maybe you can bring it up on the Maxima mailing list. best Robert Dodier -- To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
