Stop deleting your question. If you don't want it on Answers, then you should never post in the first place. Deleting the question is an insult to the person who bothered to answer your question.

Read about plot, subplot, sin
th = linspace(0,2*pi) ;
x1 = sin(th) ;
x2 = cos(th) ;
figure(1)
plot(th,x1)
figure(2)
plot(th,x1,'r') ;
hold on
plot(th,x2,'b') ;
figure(3)
subplot(121)
plot(th,x1)
subplot(122)
plot(th,x2)

this code will help you out, but i am not sure about the graph of fourth figure but x/y yields to tan graph that is what i am getting since x is sin function and y is cos function
clc
clear all
close all
a1=2;
a2=0.5;
t=0:0.01:1;
T=0.33;
y1=a1*sin(2*pi*t/T);
y2=a2*cos(2*pi*t/T);
figure
plot(t,y1)
hold on
plot(t,y2,'o')
grid on
ylabel('Time')
xlabel('Volts')
title('Your Name')
figure
subplot(2,2,1)
plot(t,3*y1)
title('3*x')
subplot(2,2,2)
plot(t,3*y2)
title('3*y')
subplot(2,2,3)
plot(t,y2.*y1)
title('x*y')
subplot(2,2,4)
plot(t,y1./y2)
title('x/y')
