Why isn't the plot showing up?

I'm supposed to have two different figures, one with a resolution of 1, one with a resolution of 0.1. Why aren't the figures showing up? Any suggestions will help.
h = 1; x = 1:h:6; y = (sqrt((x.^4)+1))/(2+sin(x)); figure(1) plot(x,y)
h = .01;
x = 1:h:6;
y = (sqrt((x.^4)+1))/(2+sin(x)); % note that when you change the x vector, you need to recompute the y vect
figure(2)
plot(x,y)

When in doubt, vectorise everything to do element-wise operations (unless you know you want to do matrix operations).
This will plot your graph:
h = .01;
x = 1:h:6;
y = (sqrt((x.^4)+1))./(2+sin(x)); % note that when you change the x vector, you need to recompute the y vect
figure(2)
plot(x,y)
Note the element-wise division (./) in your ‘y’ assignment.

Is this in a loop? Try drawnow
drawnow;
after you called plot().
