Formula for sqrt of i in limit summations?

  1. Dec 14, 2004 #1
    I can't seem to find if there is an equation for the sqrt of i or not, i know that the formula for i is (n(n+1))/2 and for i^2 its (n(n+1)(2n+1))/6, but I cant find an formula for the sqrt of i


    thanks

    There isn't one that I know of. Let me ask you something: Are you trying to do a Riemann sum for a function such as f(x)=x1/2? If so, then you might be better off using subintervals of variable width, such that the point x=ci that you use in the ith subinterval depends on i2. Then you can use your nifty little formulas.
