The factorial of a non-integer can be found using the Gamma function. This topic will explore the concept of the factorial for -1/2.

What is the Factorial of -1/2?

The factorial of a non-integer or negative number is not defined in the traditional sense, but it can be computed using the Gamma function.

The Gamma function is a continuous extension of the factorial function for real and complex numbers. For a number x, the factorial is defined as: x! = Γ(x+1) To find the factorial of -1/2, we use: (-1/2)! = Γ(1/2) We know that Γ(1/2) = √π.

Therefore, the factorial of -1/2 is √π.
