    Convergence test

    Sum from n=1 to n=infinity: [(n+1)2^n]/n!

    I need to be able to show that this series is convergent (or indeed divergent as the case may be), by using a ratio test and/or a Mclaurin series (or any test (or any series((cant afford to be fussy))for that matter))

    Dont stop the party

    PS. Can maple do series convergence test

    Use ratio test,
    \frac{(n+2)2^{n+1}}{(n+1)!}\cdot \frac{n!}{(n+1)2^n}

    Maple is for little girls. Are you a little girl?

    Wicked!

    Wild with a sharp pencil, though ... Can you suggest anything interesting for a geometry presentation: must be symmetry and congruence ( with a hint of topology (but not necessarly)) and suitable for an aged prof. Any sites?

    Be careful some of them are clever

    Just not me
