I know this integral evaluates to Pi^4/15 but I can't figure out how to do this in mathematica?(Bounds from zero to infinity.)Do I need some kind of series expansion and truncation of the series and removal of the zero point in the denominator?
Also how do I send a attachment of a mathematica notebook in this message. Attempts to use the attachment and browse option seem to result in a path to the directory where I have stored the notebook but no attachment?
