Hi all,
I'm working heavily with symbolic computation, because otherwise for the problem I'm working on, the math would be entirely unmanageable.
A problem that I've encountered (and can't seem to figure out) is that I need to perform something like this...
\sum _{n=0}^{\text{nmax}} (x-2) x f(n,x)
where the desired output corresponds to...
5 (\text{nmax}+1)-2 x f(n,x).
But the actual output given by Mathematica is
\sum _{n=0}^{\text{nmax}} (x-2) x f(n,x).
In other words, the ReplaceAll command doesn't do anything. It doesn't seem to recognize that $x^2 f(n,x)$ is present in the sum.
This is incredibly important for me to be able to continue, so I'd really appreciate if anyone knows what the problem is, or has a possible solution.
I appreciate your time.
Thanks,
Bill
