Problem 5 The first derivative 2) of a function f(x) at a point x-o can be approximated with the two-point central difference formula: dx 2h where h is a small number relative to r 0 Here is a user-defined function that calculates the derivative of a math function by using the two-point central difference formula. function dfdx2pt twoptderi (myfunc, x0,h) % dfax2pt approximates the derivative using % the two-point central difference formula % x0 is the point where the derivative is calculated % h is a number relative to XO dfdx2pt-(myfunc (x0+h)-myfunc (x0-h)/(2*h) end (a) Create the above function (please retype) (b) Use the user-defined function twoptderi (myfunc,x0,h) to calculate the following (i) the derivative of f(x)-13 at 20-0.6 and h = ii) the derivative of f(z) = 2.32x at 2.0-2.5 and h 100 100 In both cases compare the answer obtained from twoptderi with the analytical solu- tion Here is the matlab script file that you should modify clc; clear; close al1; format long % you may want to read about the 'format, myfunc -0(x) (x^3); % define the function x0-0.6; hx0/100; dfdx2pt = twoptderi (myfunc , x0 , h)
