With the help of `scipy.integrate.quad()` method, we can get the integration of a given function from limit a to b by using `scipy.integrate.quad()` method.

Syntax : `scipy.integrate.quad(func, a, b)`

Return : Return the integration of a polynomial.

Example #1 :
In this example we can see that by using `scipy.integrate.quad()` method, we are able to get the integration of a polynomial from limit a to b by using this method.

 `# import scipy.integrate.quad``from` `scipy ``import` `integrate``gfg ``=` `lambda` `x: x``*``*``2`` ` `# using scipy.integrate.quad() method``geek ``=` `integrate.quad(gfg, ``0``, ``3``)`` ` `print``(geek)`

Output :

9.000000000000002

Example #2 :

 `# import scipy.integrate.quad``from` `scipy ``import` `integrate``gfg ``=` `lambda` `x: x``*``*``2` `+` `x ``+` `1`` ` `# using scipy.integrate.quad() method``geek ``=` `integrate.quad(gfg, ``1``, ``4``)`` ` `print``(geek)`

Output :

31.5
