Question:

Find the value of  \Gamma(5/2).

Answer:

The value of  \Gamma(5/2) is  \frac{3\sqrt{\pi} }{4}.

Concept:

Gamma function (\Gamma).

\Gamma(n+1) = n \Gamma(n)        if n>0

\Gamma(n) = \Gamma(n+1)/n        if n<0

Find:

The value of \Gamma (5/2).

Solution:

5/2 can be written as (1+3/2).

\Gamma (\frac{5}{2} ) = \Gamma (\frac{3}{2}  + 1)\\

Here n = 3/2 which is greater than 0.

\Gamma (\frac{5}{2} ) = \Gamma (\frac{3}{2}  + 1)\\

       = \frac{3}{2} \ \Gamma (\frac{3}{2} )            ------------------ (i)

Now, 3/2 can be written as (1/2 + 1).

\Gamma(3/2) = \Gamma(1/2 + 1)

Here n = 1/2 which is also greater than 0.

\Gamma(3/2) = \Gamma(1/2 + 1)

          = (1/2) \Gamma(1/2)

But \Gamma(1/2) = √π

\Gamma(3/2) =  (1/2) × √π

             = √π/2

Putting the value of  \Gamma(3/2) in (i), we get

\Gamma(5/2) = (3/2)(√π/2)

           = \frac{3\sqrt{\pi} }{4}

Hence, the value of  \Gamma(5/2) is  \frac{3\sqrt{\pi} }{4}.
