Question

Matlab: please answer all 3 parts and show steps using Matlab inputs ONLY thank you

Problem 3. Consider the function f(x) ei cos(2x). (1) Sketch its graph over the interval [0, r] by the following commands: (2) Using h-001 to compute the difference quotient for x = π/6 in [0, π]. The commands are: And the difference quotient is: (3) Using h = 0.01 to approximate the second derivative by computing the difífquo for x = π/6 in [0, π]. The commands are And the difdifquo is:

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

clc
clear all
f=@(x) exp(x/2)*cos(2*x);
fplot(f,[0,pi]);
disp('Part b');
y=[f(pi/6) f(pi/6+0.01)];
x=[pi/6 pi/6+0.01];
diff(y)./diff(x)
disp('Part c');
x=pi/6;
(f(x+0.01)-2*f(x)+f(x-0.01))/0.01^2
