1. The problem statement, all variables and given/known data This is basically just a step in a problem I'm doing, but I can't find a solution for it anywhere. So, limit as n[itex]\rightarrow[/itex][itex]\infty[/itex] (2n)!/(4n(n!)2) 3. The attempt at a solution I tried writing out the factorials of the top and bottom to see if anything would cancel out, but it doesn't work, at least I don't see how. I know that it goes to 0, but I don't know how to actually compute it. Any help at all would be much appreciated.
