Strange integration behavior

jim.hagler's picture

Version 5.5, build 2960. An integral that is clearly positive is evaluated as  0. A similar integral evaluated correctly. A similar integral which evaluates correctly to a 2nd integral but then SWP hangs if I try to evaluate the 2nd integral.

Scientific WorkPlace returns

Scientific WorkPlace returns the answers given by the underlying MuPAD engine.  Note that if you choose Compute, Evaluate Numerically, then you get a positive answer.

Future version of the product should deal with this type of integration problem more appropriately.

I am not able to reproduce the problem you report concerning the hanging of SWP, however.
