Here's the code from exercise 2 : (Please finish the ex3 which will use the code from ex2 and paste the code clearly)

f=@(t,y) 1-exp(-4*t)-2*y

[T,Y]=ode45(f,[0,3],2);

hold on;

plot(T,Y,'+g');

plot(T,Y,'r')

Here's the code of Code Snippet 1

% Interval bounds

tmin =0;

tmax =3;

ymin=0;

ymax=2;

% Grid spacing

spacing = 0.3;

% Define x and y coordinates

[pt , py] = meshgrid(tmin:spacing:tmax,ymin:spacing:ymax);

% Calculate slopes

ydash = 1-exp(-4*pt)-2*py;

% Define slope vector components

dt = (spacing/2)./sqrt(1+ydash.^2);

dy = ydash.*dt;

% Clear the figure

clf;

% Create slope field

q = quiver(pt, py, dt, dy,'b','AutoScale','off');

set(q,'ShowArrowHead','off','LineWidth',1)

% Set axis and labels

axis([tmin tmax ymin ymax])

xlabel('x')

ylabel('y')

Exercise 3 The following code snippet will produce a slope field for the ODE dy di = f(t,y), y(0) = 2, Osts3 where f(t, y) = 1 e-44 2y.

Run Code Snippet 1 and by adapting your answers from Exercise 2, plot a numerically approximated solution to the IVP over the top of the slope field. Save your figure as a PNG image and submit using the following prompt. Show/hide tip on saving as a PNG To save the current figure as a PNG you can use the command: print("module10.png','-dpng') or simply select Save As... from the Figure Window. But be careful! Make sure you select the .png file type when you save your figure.
