# Python | Scipy integrate.quadrature() method

• Last Updated : 23 Jan, 2020

With the help of `scipy.integrate.quadrature()` method, we can get the computation of definite integral using fixed tolerance gaussian quadrature by using `scipy.integrate.quadrature()` method.

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

Return : Return gaussian quadrature approximation to integral.

Example #1 :
In this example we can see that by using `scipy.integrate.quadrature()` method, we are able to get the gaussian quadrature approximation to integral function from limit a to b by using this method.

 `# import scipy.integrate.``from` `scipy ``import` `integrate`` ` `gfg ``=` `lambda` `x: x``*``*``8` `+` `x``*``*``4`` ` `# using scipy.integrate.quadrature() method``geek ``=` `integrate.quadrature(gfg, ``0.0``, ``1.8``)`` ` `print``(geek)`

Output :

25.81905715199999

Example #2 :

 `# import scipy.integrate.``from` `scipy ``import` `integrate`` ` `gfg ``=` `lambda` `x: x``*``*``2` `+` `2` `*` `x ``+` `4`` ` `# using scipy.integrate.quadrature() method``geek ``=` `integrate.quadrature(gfg, ``0.0``, ``4.0``)`` ` `print``(geek)`

Output :
