Hi!: In version 3.0 (Linux and Windows) this integral isn't solved Integrate[Exp[-(Log[x/a]^2/(2*b))], x] if I do the same integral in http://www.integrals.com, is solved! (??) In Linux and Windows, if I write in the next, more complicated form Integrate[(a*Exp[b/2 - (b - Log[x/a])^2/(2*b)])/x, x] is solved! (???) Enrique Zeleny Instituto de Fisica Puebla, Mexico
