Use a midpoint sum with 10 sub-intervals to estimate the area between f (x) = x2 and the x-axis on [0,1].
If we split [0,1] into 10 sub-intervals we get sub-intervals of length .1. We need to know the following values of f:
We add them all up to get 3.325, and then multiply by 0.1 to get our estimate:
3.325(0.1) = 0.3325.
