Use the Midpoint Rule with the given value of n to approximate the integral.
10
Vx3 + 6 dx, n = 4
Step 1
We must calculate Ma = E fx)Ax = f(x1) + f(x2) + f(xg) + f(Xa) Ax,
where x1, X2, x3, X4 represent the midpoints of four equal sub-intervals of [2, 10].
| = 1
Since we wish to estimate the area over the interval [2, 10] using 4 rectangles of equal widths, then each rectangle will have width Ax =
Step 2
