Approximate

Question

∫_-2^3(x+3)dx

via the Riemann sum. Use the partition of five subintervals (of equal length), with the sample point barx_i being the right end point of the i-th interval.

I attempted this problem and got -40/3, but it's not being accepted. I'm not sure what I'm doing wrong.

Answer 1

what is the interval?

Answer 2

so, how did you do it?
If the interval is [-2,3] then each interval has length 1, so I fail to see how you got the fraction.
