Subject: Time:11:15 AM OFFICE MEMO A definite Integral Date:3/16/92 Consider the definite integral of: x^3/(Exp[x]-1) from 0 to infinity. The value is knownto be Pi^4/15. When trying to evaluate this integral in Mathematica, the application quits for no apparent reason. Macsyma gives the result: -Pi^4/15 plus terms involving Polylogarithms (with an unevaluated limit). I can't get Macsyma to "evaluate" the indicated limit. Joel Storch <storch at draper.com>
