I have a summation which runs from 1 to n. n will be a finite number, but can vary from 3 to 10 depending on the situation being solved.
I want mathematica to output the function without attempting to evaluate convergence or create a single function with n as a variable. I simply want it to output the equation starting with Sigma from 1 to n.
The function I am summing is extremely complicated, and when Mathematica attempts to carry out the summation explicitly it runs for hours and is unable to find a solution.
How can I get Mathematica to keep my output in summation form?!?! Thanks
