You can find guidelines for posting homework on this forum here. If you have trouble with Matlab basics you may consider doing the Onramp tutorial (which is provided for free by Mathworks). If your main issue is with understanding the underlying concept, you may consider re-reading the material you teacher provided and ask them for further clarification.

Are you trying to tell us that you don't know how to input n because there is no superscript on the "e" in the expression ?
You probably want to ask, "Can I put nothing in the argument?"
exp()

I am guessing that the original expression shown is supposed to be interpreted as:
Then take the hint at how to evaluate the part, and I am guessing the hint is supposed to read: exp(n) is used to evaluate
But this is just a guess, and that doesn't explain why there is a definition of i in your assignment. Maybe you can post an image of the actual assignment so we can be sure what is really being asked?

@James Tursa, guess you're right.
t = 2;
omega = 120*pi;
y = exp(- 2*t)*cos(omega*t)
But still, I wonder why is given.
