Answer to Question #168067 in MatLAB for Rj Tay

Question

Plot the following functions on the same graph for x values from -π to π. selecting spacing to create a smooth plot: y1 = sin (x) y2 = sin(2x) y3 = sin(3x)

Answer 1

x = -3.14:0.01*3.14:3.14;

y1 = sin(x);
plot(x,y1)
hold on

y2 = sin(2*x);
plot(x,y2)
hold on

y3 = sin(3*x);
plot(x,y3)
hold off
