For the function given below, nd a formula for the Riemann sum obtained by dividing the interval [all] into n equal eubintervale and using the right-hand endpoint for each ck. Then take a limit of this sum as n I no to calculate the area under the curve over [all]. x) =?x +11x2 over the interval [0,1]. Find a formula for the Riemann sum. ?[n+1) 11{n+1}{2n+1} 3\" 2n + 5
