What is the meaning of $(2n)!$ - Mathematics Stack Exchange
2015年1月27日 · Your expression for $(2n)!$ is correct. You can't easily split it down. You might want to use $$\binom {2n}{n}=\frac {(2n)!}{n!n!}=\frac {n+1}{n}\frac{(2n)!}{(n+1)!(n-1)!}=\frac {n+1}n\binom {2n}{n+1}$$ noting that $n$ and $n+1$ are coprime, or consider $$\binom {2n}{n}-\binom {2n}{n+1}$$
factorial - Simplify the expression $ (2n)!/ (2n+2)!$ - Mathematics ...
So when dividing (2n + 2)! by (2n)! only those first two factors of (2n + 2)! remain (in this case in the denominator). Very useful, thanks! Hint: One very useful property of factorials is that. (N + 1)! = (N + 1)N! (N + 1)! N! = (N + 1) Similarly, using the fact that (N + 2)! = (N + 2)(N + 1)N! will help simplify the desired quotient.

Is $(2n)!$ the same as $2(n!)$? - Mathematics Stack Exchange
2019年11月2日 · I am trying to determine the convergence of a series $$\sum_{n=17}^{\infty} \frac{(n!)}{(2n)!}.$$ Using the ratio test, I have simplified $a_{n+1}/a_n$ to $$\frac{(2n!)}{2(n)!}.$$ If $(2n)!$ is th...
How do you simplify ((2n)!)/(n!)? + Example - Socratic
2015年12月10日 · While there isn't a simplification of ((2n)!)/(n!), there are other ways of expressing it. For example ((2n)!)/(n!) = prod_(k=0)^(n-1)(2n-k) = (2n)(2n-1)...(n+1) This follows directly from the definition of the factorial function and canceling common factors from the numerator and denominator.
