For the function given below, find a formula for the Riemann sum obtained by dividing the interval [0,21] into n equal subintervals and using the right-hand endpoint for each c Subscript k. Then take a limit of this sum as n right arrow infinity to calculate the area under the curve over [0,21]. f (x )equals 441 minus x squared
