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
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
