    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 ....:)
