Homework Help: Re: Sum of infinite series - 1/n^2

  1. Oct 3, 2008 #1
    Please I have a similar problem, how can I compute the sum of this infinite series:

    SUM(X / (Y^X) ); where X(i)>0

    Is this your series?

    [tex]\sum\frac{X}{Y^X}[/tex] X(i)>0, what is X, what is Y?

    Y is a constant, while the X's are increasing from zero to infinity

    Knowing only that Xn is "some" increasing sequence there is no way to find the sum.
