原文:https://www . geesforgeks . org/python-sympy-line-minist _ angle _ between-method/
In Sympy, the function smallest_angle_between() is used to return the non-obtuse angle at the intersection of lines.
Syntax: smallest_angle_between(l2)
Parameters:
l1: LinearEntity
l2: LinearEntity
Returns: angle [angle in radians]
示例#1:
# import sympy and Point, Line, pi
from sympy import Point, Line, pi
# using Line() method
l1 = Line((0, 0), (1, 0))
l2 = Line((1, 1), (0, 0))
# using smallest_angle_between() method
rad = l2.smallest_angle_between(l1)
print(rad)
输出:
pi/4
示例#2:
# import sympy and Point, Line, pi
from sympy import Point, Line, pi
# using Line() method
l1 = Line((0, 0), (1, 0))
l3 = Line((3, 1), (0, 0))
# using smallest_angle_between() method
rad = l3.smallest_angle_between(l1)
print(rad)
输出:
acos(3*sqrt(10)/10)
