Question

must include tittle,xlabel,ylabel,and grid on. thank you

Plot the following functions using subplots in MATLAB. The independent variable should vary from 0 to 360 degrees. All the proper plot features should be incorporated in the subplots. cos (theta + 90) 3 sin (2 theta) - 2 tan (2 theta) -2sin (theta)

Answer 1

MATLAB Script:

% MATLAB Script that generates four sub plots

% Theta vector that holds values from 0 to 360
theta = linspace(0, 360);

% First Function
first = cos(theta + 90);
% Creating a sub plot
subplot(3,2,1);
% Plotting theta vs function
plot(theta, first);
% Adding title
title('cos(theta + 90)');
% Adding xlabel
xlabel('Theta');
% Adding ylabel
ylabel('cos(theta+90)');
% Turning grid on
grid on;

% second Function
second = ( 3 * sin(2*theta) ) - 2;
% Creating a sub plot
subplot(3,2,2)
% Plotting theta vs function
plot(theta, second)
% Adding title
title('3sin(2theta) - 2');
% Adding xlabel
xlabel('Theta');
% Adding ylabel
ylabel('3sin(2theta) - 2');
% Turning grid on
grid on;

% third Function
third = tan(2*theta);
% Creating a sub plot
subplot(3,2,3)
% Plotting theta vs function
plot(theta, third)
% Adding title
title('tan(2theta)');
% Adding xlabel
xlabel('Theta');
% Adding ylabel
ylabel('tan(2theta)');
% Turning grid on
grid on;

% fourth Function
fourth = (-2 * sin(theta));
% Creating a sub plot
subplot(3,2,4)
% Plotting theta vs function
plot(theta, fourth)
% Adding title
title('-2sin(theta)');
% Adding xlabel
xlabel('Theta');
% Adding ylabel
ylabel('-2sin(theta)');
% Turning grid on
grid on;
