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.
from sympy import *
x, y = symbols('x y')
gfg = cos(x).series()
print(gfg)
|
Output :
1 – x**2/2 + x**4/24 + O(x**6)
Example #2 :
from sympy import *
x, y = symbols('x y')
gfg = tan(x).series()
print(gfg)
|
Output :
x + x**3/3 + 2*x**5/15 + O(x**6)
