做雙曲線16x²-9y²=144的漸近線

1.移動K，使  \overline{ AK }垂直\overline{ KB }

即兩直線不再有交點

2.則(直線AK)會與 \overline{ KB }之中垂線L平行,

3.則此時的中垂線為雙曲線的漸近線

4.兩漸近線為4x+3y=0，4x-3y=0

B = (5, 0)
A = (-5, 0)
c = Circle(A, 6)
K = Point(c)
a = Segment(K, B)
L = LineBisector(K, B)
d = Line(K, A)
P = Intersect(L, d)
loc1 = Locus(P, K)
α = Angle(a, L)
β = Angle(d, a)
b = Line(B, P)
