# 需要导入模块: from sympy.core import C [as 别名]
# 或者: from sympy.core.C import asin [as 别名]
def angle_between(self, o):
"""Angle between the plane and other geometric entity.
Parameters
==========
LinearEntity3D, Plane.
Returns
=======
angle : angle in radians
Notes
=====
This method accepts only 3D entities as it's parameter, but if you want
to calculate the angle between a 2D entity and a plane you should
first convert to a 3D entity by projecting onto a desired plane and
then proceed to calculate the angle.
Examples
========
>>> from sympy import Point3D, Line3D, Plane
>>> a = Plane(Point3D(1, 2, 2), normal_vector=[1, 2, 3])
>>> b = Line3D(Point3D(1, 3, 4), Point3D(2, 2, 2))
>>> a.angle_between(b)
-asin(sqrt(21)/6)
