Suppose we want to compare the factorials \left( {n + 3} \right)! and \left( {n + 1} \right)! . It is easy to see that \left( {n + 3} \right)! > \left( {n + 1} \right)! is true for all values of n as long as the factorial is defined, that is, the stuff inside the parenthesis is a whole number greater than …

Web3 Answers. A good approximation for n! is that of Stirling: n! is approximately n n e − n 2 π n. So if n! = r, where r stands for "really large number," then, taking logs, you get ( n + 1 2) log n − n + 1 2 log ( 2 π) is approximately log r. Now you can use Newton's method to solve ( n + 1 2) log n − n + 1 2 log ( 2 π) = log r for n. WebMatthew Daly. The only formulas you have at your disposal at the moment is (n+1)! = (n+1) n! and 1! = 1. Using this with n=0, we would get 1! = (1) (0!) or 0! = 1!/1, so there's nothing too unnatural about declaring from that that 0! = 1 (and the more time you spend learning math, the more it will seem to be the correct choice intuitively). dx americup february 5 results
