Now we can see that the first and last terms are
Now let us consider
If we use integration by parts once we get
Now if we let
So this would gives us
Now by letting and respectively we come up with
Now making the appropriate backsubs we get
Putting this all back together we get
So putting this completely back together and remembering that we get
Can you go from there?
I know that this is beating a dead horse, but I seem to still have a problem. The integral test keeps telling me the series converges, but the graph of the equation is basically telling me that it diverges. Am I just messing myself up on this one, or did I make a mistake with the integral test?
