    (sqrt(n)/(n+100))-(sqrt(n+1)/(n+101))

    Not sure if this is the right thread to post this, but I got this kind of as home work from calculus, so basically the thing looks like this (sqrt(n)/(n+100))-(sqrt(n+1)/(n+101)) , wolfram says the answer should be n = sqrt(40001)/2 - 1/2. Anyone got any ideas?
