Homework Statement
I was just wondering if
[tex]n!=n(n-1)![/tex]
is completely general. Does it hold even for non-integer n?
Factorial Function: Does it Hold for Non-Integer N?
Click For Summary
SUMMARY
The factorial function, defined as n! = n(n-1)!, is strictly applicable to non-negative integers. However, the concept can be extended to non-integer values through the use of the gamma function, represented as Γ(z) = ∫₀^∞ t^(z-1) e^(-t) dt. This function maintains the property that Γ(z) = (z-1)! for positive integers and is defined for all complex numbers except negative integers. Thus, while traditional factorials do not hold for non-integers, the gamma function provides a valid extension.
