在Sympy中,該函數
is_perpendicular()
用於檢查兩個線性實體是否垂直。用法: Line.is_perpendicular(l2) 參數: l1: LinearEntity l2: LinearEntity 返回: True: if l1 and l2 are perpendicular, False: otherwise.
範例1:
# import sympy and Point, Line
from sympy import Point, Line
p1, p2, p3 = Point(0, 0), Point(1, 1), Point(-1, 1)
l1, l2 = Line(p1, p2), Line(p1, p3)
# using is_perpendicular() method
isPerpendicular = l1.is_perpendicular(l2)
print(isPerpendicular)
輸出:
True
範例2:
# import sympy and Point, Line
from sympy import Point, Line
p1, p2, p3 = Point(0, 0), Point(1, 1), Point(5, 3)
l1, l2 = Line(p1, p2), Line(p1, p3)
# using is_perpendicular() method
isPerpendicular = l1.is_perpendicular(l2)
print(isPerpendicular)
輸出:
False
