Taylor series

  1. Oct 12, 2011 #1
    Show that, with an appropriate choice of constant c, the taylor series of

    (1+cx)ln(1+x)

    has terms which decay as 1/n^2

    I know that ln(1+x) decays as 1/n, but I don't know how to show the above. Please help.

    Thanks in advance

    It's against the forum rules to post the exactly same question in two different subforums. You should delete one of them.

    My apologies, I am just beginning to use this forum. I did not know how to delete them, so I just cleared the content within the others.

    By the way, welcome to the forum and I'm sorry I got a bit snippy there. I tend to do that (this is not a forum for the thinskinned) without thinking about significant things like, hey you're new here.

    What's even worse is that after giving you a hard time I can't even answer your question. Fortunately for you, not everyone here is as useless as I am.
