Hi,
Can somebody please tell me how to find the sum of the following alternating series?
\sum_{n=0}^{\infty} (-1)^n exp(-5*n)/(2*n+1)
Thanks,
If you take the integral of the geometric series
term-by-term, you get
That gives you the 2n+1 in the denominator. I think that by setting x to a strategic value and multiplying by constants inside and outside of the sum, you'll be able to come up with the answer.
