n! ... is read "n" factorial.
e.g.
familiar with the ratio test for convergence/divergence ?
hey first of all i d like to start this problem off with saying i have no idea what the ! means so i cant even start this problem.. even if the ! wasnt there i d assume this was a geometric series since its in that section of the book. Other then that i know if it converges i need to find the sum. any help appreciated.
