Matlab help

Show matlab scripts and plots for parts a,b, c

Thanks

% start stepsize stop

t=linspace(0,2*pi(),100);

y = sin(t);

plot(t, y);

title('Demo of Simple Plotting');

xlabel('Time - s');

ylabel('y - ft');

pause % hit enter to go to the next plot

z=exp(-t/2) .* (3*t) .^ 2; % What are these dots????

plot(t,z);

title('Demo of Simple Plotting');

xlabel('Time - s');

ylabel('z - ft');

pause % hit enter to go to the next plot

plot(t,y,'r',t,z,'g');

title('Demo of Simple Plotting');

xlabel('Time - s');

ylabel('y and z - ft');

legend('sin(x)','(3t)^2 * exp(-t/2)');

pause % hit enter to go to the next plot

2. Modify SimplePlotting.m to do the following: a) Plot esinxx 2 ( ) from x=0 to x=6 pi, using 500 points, titles and labels b) Plot excos(2)2x from x=0 to x=6pi, using 500 points, titles and labels c) Plot both on the same graph, using titles, labels and a legend
