A few things:
1. I think your variable Estimate is defined incorrectly. Check to make sure it matches the equation in your pdf.
2. No need for the line of code Previous = count.
3. You are not summing the terms in the series. So when you define Estimate, it should be something like:
Estimate = Estimate + ...
4. Now to display the current value so you can watch it as it converges, I suggest putting something like fprintf inside your while loop:
fprintf('%d\t%0.3f\n',count,Estimate);
Make sure to put semicolons at the end of each variable definition so they do not print to the Command Window.
Hope this helps.
