use upper and lower Riemann sums for the integral sqrt(x),from 0 to 64, on the interval [0,64] with 64 equal subintervals to find upper and lower bounds for SIGMA n=1~64 sqrt(n).

what are the answers for upper and lower??

if the question were 5 equal intervals then i could solve it by hand, but 64!!! are there any shortcut or something that i can do?

thankyou
