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.

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() methodgeek = 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() methodgeek = integrate.quadrature(gfg, 0.0, 4.0)  print(geek)

Output :

53.33333333333333
