Question

Let f(x) = x2 and compute the Riemann sum of f over the interval [8,10], using the following number of subintervals (n). In each case, choose the representative points to be the left endpoints of the subintervals. (Round your answers to two decimal places.)

a)Use two subintervals of equal length (n = 2).

Answer 1

sorry its supposed to say f(x)=x^2

Answer 2

Does anyone know about this formula of Riemann??

Answer 3

my notes doesn't help much with understanding the set up of the formula

Answer 4

i'm googling it now

Answer 5

ok, so you're gonna approximate the area under the curve using two subintervals...[8,9] and [9, 10]. the width of each of these subintervals is 1.
