Question

find the formula for the Riemann sum obtained by dividing the interval [a,b] into n equal subintervals and using the right hand endpoint for each ck. Then take the limit of these sums as n tends to infinity to calculate the area under the curve over [a,b]. f(x)= 3x+2x^2 over the interval [0,2]

Answer 1

((b-a)/n)=size of interval
(0,first interval(#)=(3(#)+2(#)^2)*width of interval
if n tends to infinity, than the limit would be 0
