Hey I have a considerably long formula involving binomial coefficients. I wish to tell Mathematica to give a (symbolic) representation of these binomial coefficients, but I don't know how. For example in I would like to get How can I do that? I appreciate your help! Cheers, maxiim

Generally Mathematica is pretty stupid. You should be able to do it with something like Code: f[x_] := LeafCount[x]  Count[x, _Binomial, {0, Infinity}] + 15 Count[x, _Plus, {0, Infinity}] Simplify[(n  2) (n  1) A + (n  3) (n  2) (n  1) B, ComplexityFunction > f] Code: Simplify[Hold[3! A Binomial[n, 3]/n + 4! B Binomial[n, 4]/n], ComplexityFunction > f]

Hi CRGreathouse Thx for your answer. Quote:
Back to the problem: Id like Mathematica to transform the expression I have, that is to the representation with binomial coefficients without having to type all of them manually. (I have a large number of terms, so it would be very helpful). In more general terms, is it possible to transform a given expression in terms of builtin Mathematica functions? cheers, maxiim
