示例1: angle_between
# 需要导入模块: from sympy.core.basic import C [as 别名]
# 或者: from sympy.core.basic.C import acos [as 别名]
def angle_between(l1, l2):
"""
Returns an angle formed between the two linear entities.
Description of Method Used:
===========================
From the dot product of vectors v1 and v2 it is known that:
dot(v1, v2) = |v1|*|v2|*cos(A)
where A is the angle formed between the two vectors. We can
get the directional vectors of the two lines and readily
find the angle between the two using the above formula.
"""
v1 = l1.p2 - l1.p1
v2 = l2.p2 - l2.p1
return C.acos( (v1[0]*v2[0]+v1[1]*v2[1]) / (abs(v1)*abs(v2)) )
