 Dear arauka


If n is a positive rational number ,then the improper integral


o e-x xn-1 dx  is define as Gamma Function and is denoted by n"


 


Γn = o e-x xn-1 dx     where x ε Q+


this is very special type of intigration you can directlt calculate these type of intigration by using gamma function.


for example you want to calculate


 o e-x x3 dx 


then according to gamma function


o e-x x3 dx =o e-x x4-1 dx


                         =Γ4=3! =6


where Γ(n+1) =n!
