 Author Comment/Response igor igel 06/20/12 06:17am Hi, what does it mean when one gets the Input as an Output when trying to solve some symbolic problem? In practice we have following function: Product[(1/\[Sqrt](2 \[Pi] ( i/n b0^2 + (n - i)/n b1^2)) E^(-(1/ 2) (i/n m0 + (n - i)/n m1 - x)^2/( i/n b0^2 + (n - i)/n b1^2)))^(1/n), {i, 1, n}] After evaluating and then FullSimplify we get: (2 \[Pi])^(-(1/ 2 )) (((b0 - b1) (b0 + b1) (m0 - m1) (-b1^2 (m0 + m1 (-1 + n) + 3 m0 n - 4 n x) + b0^2 (m0 - m1 + m0 n + 3 m1 n - 4 n x)) + 2 n (b1^2 (m0 - x) + b0^2 (-m1 + x))^2 (HarmonicNumber[(b0^2 n)/(b0^2 - b1^2)] - HarmonicNumber[(b1^2 n)/(b0^2 - b1^2)]))/( 4 (b0 - b1)^3 (b0 + b1)^3))/ Sqrt[(((b0 - b1) (b0 + b1))/n)^ n Pochhammer[1 + (b1^2 n)/(b0^2 - b1^2), n]] but unfortunatly Lim[%,n->Infinity] is returning the argument. Assumptions are: \$Assumptions = b1 > 0 && b1 > 0 && m0 \[Element] Reals && m1 \[Element] Reals && x \[Element] Reals && n \[Element] Integers && n > 0 I would appreciate any ideas very much. igor igel URL: ,
