I am looking for a way to sum some numbers. I understand that if I want to sum pi, I can use the geometric series:
[itex]\sum\limits_{i=0}^N p^{i} = \frac{1-p^{N+1}}{1-p}[/itex]
But can anyone help me with what to do when I need:
[itex]\sum\limits_{i=0}^N p^{i} q^{ti}[/itex]
where t is just a constant.
Thank you in advance of any help!
