Last Updated : 10 Jul, 2020

With the help of singularityintegrate() method, we can get the definite integral of the singularity functions and return the integrated function by using this method.

Syntax : singularityintegrate(f, x)

Return : Return the definite integral of function.

Example #1 :

In this example we can see that by using singularityintegrate() method, we are able to get the definite integral of a singularity function by using this method and return the integrated function.

Python3

# import singularityintegrate 
from sympy.integrals.singularityfunctions import singularityintegrate 
from sympy import SingularityFunction, symbols, Function 
  
x, a, n, y = symbols('x a n y') 
f = Function('f') 
  
# Using singularityintegrate() method 
gfg = singularityintegrate(SingularityFunction(x**2 + 1, a, 2), x) 
  
print(gfg)

Output :

SingularityFunction(x**2 + 1, a, 3)/3

Example #2 :

Python3

# import singularityintegrate 
from sympy.integrals.singularityfunctions import singularityintegrate 
from sympy import SingularityFunction, symbols, Function 
  
x, a, n, y = symbols('x a n y') 
f = Function('f') 
  
# Using singularityintegrate() method 
gfg = singularityintegrate(SingularityFunction(x**3, 4, -2), x) 
  
print(gfg)

Output :

SingularityFunction(x**3, 4, -1)
