原文:https://www.geesforgeks.org/python-sympy-line-is_parallel-method/
In Sympy, the function is_parallel() is used to check whether the two linear entities are parallel or not.
Syntax: Line.is_parallel(l2)
Parameters:
l1: LinearEntity
l2: LinearEntity
Returns:
True: if l1 and l2 are parallel,
False: otherwise.
示例#1:
# import sympy and Point, Line
from sympy import Point, Line
p1, p2 = Point(0, 0), Point(1, 1)
p3, p4 = Point(3, 4), Point(6, 7)
l1, l2 = Line(p1, p2), Line(p3, p4)
# using is_parallel() method
isParallel = Line.is_parallel(l1, l2)
print(isParallel)
输出:
True
示例#2:
# import sympy and Point, Line
from sympy import Point, Line
p1, p2 = Point(0, 0), Point(1, 1)
p3, p4 = Point(3, 4), Point(6, 6)
l1, l2 = Line(p1, p2), Line(p3, p4)
# using is_parallel() method
isParallel = Line.is_parallel(l1, l2)
print(isParallel)
输出:
False
