Hi friends,

can anyone plz help me out in solving this problem.

The problem goes something like this.

Derive a formula to find the sum of the following series.

sqrt(1)+sqrt(2)+sqrt(3)+sqrt(4)+ - - - - - - - - - - - +sqrt(n) where
n>=1

regards,
karthik.

I don't think there's a simple closed form expression for
this sum, but you can use left-endpoint and right-endpoint
Riemann sums for y = sqrt(x) with delta(x) = 1 on the
interval [0,n] to see that a rough estimate for the
sum is n^(3/2). For slightly more details on this,
see my post at
