This looks like a homework problem. If you have any questions ask your instructor or read the link below to get started:

How do I get help on homework questions on MATLAB Answers? - MATLAB Answers - MATLAB Central

Obviously we can't give you the full solution because you're not allowed to turn in our code as your own.

Generic hint:

numPoints = 300;
t = linspace(0, 100, numPoints);
omega = .02;
y = 10 * sin(2 * pi * omega * t);
plot(t, y, 'b-', 'LineWidth', 2);
grid on;
xlabel('t')
ylabel('y')

@Dyuman Joshi That was just boilerplate reply inserted from my list of "Quick replies" and I didn't take the time to customize it. Have you tried the quick replies yet? I use them a lot.

[Dyuman Joshi]

Yes, I have 7 quick replies ready to go, which I use often.
