scipy.integrate package in SCIPY

It is used to calculate mathematical integration based formula.

Example of Single Integration in SCIPY:- 

import scipy.integrate
from numpy import exp
f= lambda x:x*x
i = scipy.integrate.quad(f, 0, 1)
print(i)
Example of double integration ion SCIPY:-

import scipy.integrate 

from numpy import exp

from math import sqrt

f = lambda x, y : 16*x*y

g = lambda x : 0

h = lambda y : sqrt(1-4*y**2)

i = scipy.integrate.dblquad(f, 0, 0.5, g, h)

print(i)

Fixed Quad Integration:-

from scipy import integrate 
  
  
def func(x): return 3*x**3
  
  
# using scipy.integrate.fixed_quad() method 
# n is the order of integration 
gfg = integrate.fixed_quad(func, 1.0, 2.0, n=2) 
  
print(gfg) 

scipy.nquad:-

from scipy.integrate import nquad 


def f(x, y, z): 
	return x*y*z 


I = nquad(f, [[0, 1], [0, 5], [0, 5]]) 
print(I)
