原文:https://www.geesforgeks.org/python-sympy-encloss_point-method/
In sympy, the function encloses_point() is used to check whether the given point is encolsed by given ellipse or not.
Syntax: Ellipse.encloses_point(point)
Return: True:if point is enclosed by ellipse, otherwise False.
示例#1:
# import sympy and geometry module
from sympy import *
from sympy.geometry import *
x = Point(0, 0)
# making ellipse with given point as center and radii
e1 = Ellipse(x, 3, 2)
# using encloses_point() method
isEnclosed = e1.encloses_point((0, 0))
print(isEnclosed)
输出:
True
示例#2:
# import sympy and geometry module
from sympy import *
from sympy.geometry import *
x = Point(3, 1)
# making ellipse with given point as center, hradius and eccentricity
e2 = Ellipse(x, hradius = 3, eccentricity = Rational(4, 5))
# using encloses_point() method
isEnclosed = e2.encloses_point((4, 6))
print(isEnclosed)
输出:
False
