Hi, I'm working on a continuous time random walk problem, but my question is to do with analysis.
I have and infinite sum and am unsure how to get form one step to the next or whether it is just a standard result.
The variables aren't important but it looks like
sum from n=0 to inf of (p^n((1-p)/s)(cos(ka))^n) = ((1-p)/s)(1/(1-pcos(ka))
sorry it looks messy but i was struggling with the latex.
Is this a standard result or is there a trick I can apply?
Thanks
