Look at the article "Some Divergent Trigonometric Integrals" by Erik Talvila in The American Mathematical Monthly Vol. 108 No. 5 (may 2001). This article deserves discussion on this newsgroup. I don't know why I haven't seen any. It's embarassing when Mathematica gets the wrong answer, but on the other hand it happens so rarely I guess you can write a journal article about it!
