Python | sympy.series() method

With the help of sympy.series() method, we can find the series of some mathematical functions and trigonometric expressions by using sympy.series() method.

Syntax : sympy.series()

Return : Return a series of functions.

Example #1 :
In this example we can see that by using sympy.series() method, we are able to find the series of some trigonometric functions.

# import sympy
from sympy import *

x, y = symbols('x y')

# Use sympy.series() method
gfg = cos(x).series()

print(gfg)

Output :

1 – x**2/2 + x**4/24 + O(x**6)

Example #2 :

# import sympy
from sympy import *

x, y = symbols('x y')

# Use sympy.series() method
gfg = tan(x).series()

print(gfg)

Output :

x + x**3/3 + 2*x**5/15 + O(x**6)
