Be very (really very) careful with any result of Integrate, especially if you do a definite integral. If there are functions involved with branch cuts (in the integrand as well as in the result) it is quite probable that Mathematica puts it on the wrong sheet of the Riemann plane. One day I supported this to Wolfram Research as a bug. They never could convince me that it is a feature ;-). -- Hendrik van Hees Fakultät für Physik Phone: +49 521/106-6221 Universität Bielefeld Fax: +49 521/106-2961 Universitätsstraße mailto:hees at physik.uni-bielefeld.de D-33615 Bielefeld
