Homework Statement
It's from sum (n=1, to infinity.. I apologize for not knowing how to type it in properly!) of (n!)/(2n)!
Homework Equations
The Attempt at a Solution
We're supposed to use either the Root Test or the Ratio Test to determine if the series converges or not. My problem is that I don't know how to break up (2n!) so that it'll cancel with (n!). Any hints are appreciated. Thank you!
