determine whether the series converges of diverges

the sum from k=1 to infinity of

cos(e^-k)

I'm not sure where to start..

  • calculus - ,

    As k becomes very large, e^-k approaches zero, and every cos(e^-k) term approaches 1.
    You end up with an infinite series of terms all approaching +1, which cannot converge
