Video that explains the complex exponential

While writing the second part of the Fourier tutorial, I came across this video which does a great job of explaining the complex exponential, its relationship to sinusoids and hence to the reason why signal processing math is done with exponentials. Nicely done.http://www.youtube.com/watch?v=6geNX1F34I8

    My professor recommended your site and thank goodness I saved all her suggested reading. I’m a nerd at heart and would to say thank you for tutorials. Have a blessed day.

    Oops. I meant to say I would like to say thank you for your tutorials, Mam. Pardon syntax. I know better.
