Python | sympy.integrate() method

With the help of sympy.integrate() method, we can find the integration of mathematical expressions in the form of variables by using sympy.integrate() method.

Syntax : sympy.integrate(expression, reference variable) Return : Return integration of mathematical expression.

Example #1 : In this example we can see that by using sympy.integrate() method, we can find the integration of mathematical expression with variables. Here we use symbols() method also to declare a variable as symbol.

Python3 1=1

# import sympy
from sympy import * x, y = symbols('x y')
gfg_exp = sin(x)*exp(x)

print("Before Integration : {}".format(gfg_exp))

# Use sympy.integrate() method
intr = integrate(gfg_exp, x)

print("After Integration : {}".format(intr))

Output :

Before Integration : exp(x)*sin(x) After Integration : exp(x)*sin(x)/2 - exp(x)*cos(x)/2

Example #2 :

Python3 1=1

# import sympy
from sympy import * x, y = symbols('x y')
gfg_exp = sin(x)*tan(x)

print("Before Integration : {}".format(gfg_exp))

# Use sympy.integrate() method
intr = integrate(gfg_exp, x)

print("After Integration : {}".format(intr))

Output :

Before Integration : sin(x)*tan(x) After Integration : -log(sin(x) - 1)/2 + log(sin(x) + 1)/2 - sin(x)
