Python | Scipy integrate.quad() method

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
