The correct thing has been printed out by Mathematica. I think you meant to evaluate Product[1/(1 + Exp[x]), {x, n}] -- Steve Luttrell West Malvern, UK "wuzzy" <mypcos at hotmail.com> wrote in message news:b22jn1$6be$1 at smc.vnet.net... > What is the Mathematica notation for the i'th x in y=f(x) > > -wuzzy > > for instance I'd like to find a simplified algebraic expression for > Product[1/(1 + e^(x)), {i, n}] > > where there are n values of x. > > for the above, mathematica just prints out: > [1/(1+e^(x)]^n >
