Plot 2D graph

Plot 2D graphs for each of the following functions on an interval [−2π, 2π]. Then plot all the graphs in the same chart and add a title to the graph. sin(x); 2sin(x);3sin(x); 5sin(x); sin(2x); sin(3x); sin(5x)

Answer 1

[Jim Riggs]

Put all the graphs on a single figure:

x=-2*pi:0.04:2*pi;
figure;
plot(x,sin(x),'r');
hold on;
plot(x,2*sin(x),'b');
plot(x,3*sin(x),'g');
plot(x,5*sin(x),'c');
plot(x,sin(2*x),'y');
plot(x,sin(3*x),'m');
plot(x,sin(5*x),'k');
grid on;
title('Figure title');

To make individual graphs:

figure:
plot(x,sin(x),'r');
grid on;
title('Sin(x)');

Next figure:

figure;
plot(x,2*sin(x),'b')
grid on;
title('2*Sin(x)');

etc.

Answer 2

[Jagar]

x=-2*pi:0.04:2*pi; 
figure;
plot(x,sin(x),'r');
hold on;
plot(x,2*sin(x),'b'); 
plot(x,3*sin(x),'g'); 
plot(x,5*sin(x),'c');
plot(x,sin(2*x),'y'); 
plot(x,sin(3*x),'m');
plot(x,sin(5*x),'k');
grid on; 
title('Figure title');
