Python | Sympy 椭圆. director_circle()方法
原文:https://www.geesforgeks.org/python-sympy-ellipse-director_circle-method/
In Sympy, the function director_circle() returns a Circle consisting of all points where two perpendicular tangent lines to the ellipse cross each other.
Syntax: Ellipse.director_circle()
Returns: Circle
A director circle returned as a geometric object.
示例#1:
# import sympy and Circle, Ellipse, Point
from sympy import Circle, Ellipse, Point
p = Point(3, 8)
# using director_circle() method
directorCircle = Ellipse(p, 7, 9).director_circle()
print(directorCircle)
输出:
Circle(Point2D(3, 8), sqrt(130))
例 2:
# import sympy and Circle, Ellipse, Point, symbols
from sympy import Circle, Ellipse, Point, symbols
p = Point(3, 8)
a, b = symbols('a b')
# using director_circle() method
directorCircle = Ellipse(p, a, b).director_circle()
print(directorCircle)
输出:
Circle(Point2D(3, 8), sqrt(a**2 + b**2))
