Plot the real part of v(t) = 1.414e^(-j377*t).

I'm not sure what the professor wants for this problem so any help on how to do this would be appreciated!

Do you know the relationship.....?

\(e^{-j\theta}=cos\theta+jsin\theta\)

So

\(Re(e^{-j\theta})=cos\theta\)

This might help you to the next step.

Sorry - I think I should have

\(e^{-j\theta}=cos\theta-jsin\theta\)

But the next step in the process required will be the same ....
