Problem 12

(a) If $ f(x) = \ln x $, $ 1 \le x \le 4 $, use the commands discussed in Exercise 11 to find the left and right sums for $ n $ = 10, 30, and 50.

(b) Illustrate by graphing the rectangles in part (a).

(c) Show that the exact area under $ f $ lies between 2.50 and 2.59.


(A). $L 10 \approx 2.331630 R 10 \approx 2.747518 L 30 \approx 2.475238 R 30 \approx 2.613867 L 50 \approx$ 2.503364$R 50 \approx 2.586541$

so improbable I explained how to compute or how to estimate the area under F by using eleven point and right in point. That's eleven Royce Somes for a general. Former, please take a look at that problems and you can plug in the specific A function here and the specific values here and for the answer of this problem.
