Python| Sympy equation() 方法
在 Simpy 中,函数
equation()
用于生成给定圆的方程。 Syntax : equation(x='x', y='y')
Parameters:
x : str or Symbol, optional
y : str or Symbol, optional
Returns : SymPy expression
示例 #1:
# import sympy, Point and Circle
from sympy import Point, Circle
# using Circle()
c1 = Circle(Point(0, 0), 5)
c2 = c1.equation()
print(c2)
输出:
x**2 + y**2 - 25
示例 #2:
# import sympy, Point and Circle
from sympy import Point, Circle
# using Circle()
c3 = Circle(Point(1, 2), 5)
c4 = c3.equation()
print(c4)
输出:
(x - 1)**2 + (y - 2)**2 - 25
