Gamma
 Usage
Notes
 Further Examples
Here are the first  integer values of the gamma function; these are the factorials offset by  .
In[1]:=
|
Out[1]=
|
The gamma function generalizes factorials to numbers beyond the positive integers.
In[2]:=
|
Out[2]=
|
This is the derivative.
In[3]:=
|
Out[3]=
|
This is the series expansion around  to order  .
In[4]:=
|
Out[4]=
|
Here is the series expansion around  to order  for the incomplete gamma function.
In[5]:=
|
Out[5]=
|
This simplifies an expression involving the gamma function.
In[6]:=
|
Out[6]=
|
Here are some integrals that evaluate to expressions involving the gamma function.
