Hi everyone,

I have an expression for a summation and want to find out where it converges precisely. I decided to work out the sum for i=10,100,1000 etc. I logged the results, then took the recriprocal and then plotted it as the x-axis in Excel with the y-axis as my result. (So that the y intercept gives the convergence value).

So now I want to repeat this in Mathematica. I tried plotting my summation for different values of i, but it just didn't like that one bit because i is discrete and not continuous. So firstly, how do I do this? I'm thinking ListPlot?

Secondly, I need to be able to fit a polynomial function to the result, which I also have no idea how to do. I have attached the notebook.

I really appreciate any help,

Thanks,

Natski
