Definite Integration using Python

 

import sympy as sp

x = sp.Symbol('x')

f = input("Enter the function(in terms of x):")

F_indefinite = sp.integrate(f, x)

print("Indefinite integral ∫f(x) dx =", F_indefinite)

a = float(input("Enter the lower limit of integration: "))

b = float(input("Enter the upper limit of integration: "))

F_definite = sp.integrate(f, (x, a, b))

print(f"Definite integral ∫f(x) dx from {a} to {b} =", F_definite)

Indefinite integral ∫f(x) dx = x**3/3 + 3*x

Definite integral ∫f(x) dx from 9.0 to 27.0 = 6372.00000000000
