The question I've been posed is:
Show that the following series converges, and compute its value
From this I decided to use partial fractions to put into the form:
And from this I noticed that this is in the form of a telescoping series which I think would cancel down to:
So I've got to this point, but I don't think what I've worked out is substantial enough to prove what I've been asked.
Would anyone mind giving any tips to make my working more thorough.
