Python | sympy.simplify() method (original) (raw)

Last Updated : 1 May, 2023

With the help of sympy.simplify() method, we can simplify any mathematical expression.

Syntax: simplify(expression)

Parameters:
expression - It is the mathematical expression which needs to be simplified.

Returns: Returns a simplified mathematical expression corresponding to the input expression.

Example #1: In this example we can see that by using sympy.simplify() method, we can simplify any mathematical expression.

Python3 `

import sympy

from sympy import *

x = symbols('x') expr = sin(x)**2 + cos(x)**2

print("Before Simplification : {}".format(expr))

Use sympy.simplify() method

smpl = simplify(expr)

print("After Simplification : {}".format(smpl))

`

Output:

Before Simplification : sin(x)**2 + cos(x)**2 After Simplification: 1

Example #2:

Python3 `

import sympy

from sympy import *

x = symbols('x') expr = (x3 + x2 - x - 1)/(x**2 + 2 * x + 1)

print("Before Simplification : {}".format(expr))

Use sympy.simplify() method

smpl = simplify(expr)

print("After Simplification : {}".format(smpl))

`

Output:

Before Simplification : (x3 + x2 - x - 1)/(x*2 + 2x + 1) After Simplification : After Simplification : x - 1
