Question

Use a finite sum to estimate the area under the curve using the midpoint rule

f(x)=x^3 on the interval [0,2]

using two rectangles and four rectangles

show all work

Expert Solution
Step 1

Width of the interval [0,2] is = 2-0=2So for two rectangles the width of the subintervals=x=22=1So the partition is= 0,1,2So the midpoints are 0.5 and 1.5So the estimated area is:x[f(0.5)+f(1.5)]=10.53+1.53=3.5
