Python | Sympy equation() method

In Simpy, the function equation() is used to make equation of a given circle.

Syntax : equation(x='x', y='y')

Parameters:
x : str or Symbol, optional
y : str or Symbol, optional

Returns : SymPy expression

Example #1:

# import sympy, Point and Circle
from sympy import Point, Circle

# using Circle()
c1 = Circle(Point(0, 0), 5)
c2 = c1.equation()

print(c2)

Output:

x**2 + y**2 - 25

Example #2:

# import sympy, Point and Circle
from sympy import Point, Circle

# using Circle()
c3 = Circle(Point(1, 2), 5)
c4 = c3.equation()

print(c4)

Output:

(x - 1)**2 + (y - 2)**2 - 25
