PLEASE HELP, PLEASE SHOW WORK2.14. The numerical integral Г of a function/ x) may be obtained by the -1, which involves summing the function values at various x values, x,-a + i Δ. for . . , so that n Δx-b-a, Xo a, and xn-l-b-Δ. Using this formula, which is known as the rectangular rule, compute the integral simple expression f(x)dr * (xJAX -x-dx for Δx 2, 1, 0.5, 0.1, 0.05, and 0.01 . Compare the results obtained with the exact value of 8/3. Plot the numerical error versus the step size Δx. What value of Δx will you choose for such computa- 0 tions, on the basis of the results obtained?
