PLEASE SOLVE JUST PROBLEM 2. I NEED IT IN TYING NOT HANDWRITTEN. I shall be very thankful to you.

All problems are from the textbook by V.L. Law. Submit the spreadsheet (.xlsx or .xls file without macro, or .xlsm with macro) on blackboard, "Problem Sets" tab. If you submit twice or more, the last attempt will be graded. If you want to explain something, put that in a text box in the spreadsheet. Do NOT submit an image of a hard copy on blackboard, Problem 1 (6 pts). Exercise 4.5. In part a, for numerical derivatives, use central differencing and second- order correct approximations for intermediate and end points, respec- tively. Also, for comparing the numerical derivatives at each point with the exact values, create a column and calculate the percent error, In part b, instead of calculating the percent error at x = 1, create a column and calculate the percent error for all points. Note that the exact integral is: | = cos(ar)dr = 2x cos(x) + (x2 2) sin(x). (1) Problem 2 (6 pts). Exercise 4.4. In part a, use Simpson's rule instead of trapezoidal rule. To experiment with Ar, use Ar = 0.1 and 0.01 only. In each case, for comparison of results, only calculate the percent error using exact solution (2/3). In part b, in each case, for comparison of results, only calculate the percent error using exact solution (2/3). Problem 3 (6 pts). Exercise 4.1. In part b, for curve fitting, use a linear function. Also, for comparing the results with those of part a, only compare the average heat capacity of part a with that of part b. . In part c, for comparing C, with those from nist database, create a column and compute the percent error of Cp, assuming that C, from Page 1 of 2 All problems are from the textbook by V.L. Law.
