在Sympy中,該函數
parallel_line()
用於創建新直線,該新直線平行於給定線性實體,並穿過給定點p。Synatx: Line.parallel_line(p) 參數: p: Point 返回: Line
範例1:
# import sympy and Point, Line
from sympy import Point, Line
p1, p2, p3 = Point(0, 0), Point(2, 3), Point(-2, 2)
l1 = Line(p1, p2)
# using parallel_line() method
l2 = l1.parallel_line(p3)
# checking l2 is parallel to l1 using is_parallel() method
isParallel = l1.is_parallel(l2)
print(isParallel)
輸出:
True
範例2:
# import sympy and Point3D, Line3D
from sympy import Point3D, Line3D
p1, p2, p3 = Point3D(0, 0, 0), Point3D(2, 3, 4), Point3D(-2, 2, 0)
l1 = Line3D(p1, p2)
# using parallel_line() method
l2 = l1.parallel_line(p3)
# checking l2 is parallel to l1 using is_parallel() method
isParallel = l2 = l1.is_parallel(p3)
print(isParallel)
輸出:
True
