Evaluating Infinite Series

  1. Dec 14, 2006 #1
    How do I evaluate the infinite series (2^n)/(n!) from n=0 to infinity?
    (I dont know how you put the little E symbol and all that in so I had to write it out.)

    I already found that it converges to 0 using the ratio test, but I dont know quite how to evaluate it.

    Any help would be mondo appreciated! Thank you!!!

    Have you dealt with Taylor's series? In particular, do you know the Taylor's series for ex?

    We went over them, but I'm not sure how to use them...
