Hi
I was trying to solve the equation (m + n)!/m! = v for "n" and found an online calculator http://www.hostsrv.com/webmab/app1/MSP/quickmath/02/pageGenerate?site=quickmath&s1=equations&s2=solve&s3=advanced#reply" which spit out the following as a solution:
n = factorial(-1)[vm!] - m
I Googled "inverse factorial" and searched on wolfram.com and wikipedia.com but didn't find a clear answer as to what inverse factorials are, much less how to calculate them.
Factorials are so simple to calculate (1 x 2 x 3 ... x n) do inverse factorials have a similarly simple method?
Thanks for any help
