How do you plot three equations in matlab?

Answer 1

To plot three equations in MATLAB, you can use the fplot function for each equation or define them as functions. For example, you can create a script like this:

f1 = @(x) x.^2;  % First equation
f2 = @(x) x + 2; % Second equation
f3 = @(x) sin(x); % Third equation

fplot(f1, [-10, 10], 'r'); hold on; % Plot first equation in red
fplot(f2, [-10, 10], 'g');          % Plot second equation in green
fplot(f3, [-10, 10], 'b');          % Plot third equation in blue
hold off; grid on; legend('y=x^2', 'y=x+2', 'y=sin(x)');

This code sets the range for the x values, specifies colors for each plot, and adds a legend for clarity.
