A problem of infinite series

  1. Apr 9, 2007 #1
    I don't know how to get a analytic expression of this infinite series:
    [tex]\sum_{n=0}^{+\infty} \frac{1}{1+x^n}[/tex]
    here [tex]x>1[/tex].

    Thanks!

    Probably completely useless- but

    S=1/2+1/([x^1.2]-1)

    gives an empirically reasonable fit

    The 'smart' bit is a compliment, the *** bit- not so much.

    It's all a compliment! Just in a snarky way. Don't worry- I just express myself sarcastically. I thought you might know the answer to the above math problem. Sorry if I worried you!

    Ok I stuck here lol. What level of mathematics did you get this question from, and are you sure it even has a solution?

    Have you done Hyper geometric series yet?

    EDIT: Forget the hypergeometric series, all I get is nested series.

    Please some Admins or someone better at math than me, help me! Seeing as the OP hasn't come back yet and has only 1 post, maybe this person found out the question has no solution...
