Thread: setting up limit expressing area

How would I do this problem? Set-up the limit expressing the exact area below f(x) = 4x^2-x^3 and above the x-axis over the interval [-1,0] using even sub-intervals and right endpoints for c sub i.
then evaluate the area using the fnint feature of your calculator.

If we let be the number of even sub-intervals, then what is the width of each sub-interval?
