Inversion der

Strophoide

r( t)=\frac {1-sin(t)}{cos(t)}

r( t)=\frac {1+sin(t)}{cos(t)}

Ha 05

α=t

Ziehe t.

O = (0, 0)
c = Circle(O, 1)
t = 0.33 (slider from -1.4 to 5, step 0.01)
A = Intersect(c, xAxis, 2)
B = Rotate(A, t, O)
α = Angle(A, O, B)
r_1: (1 - sin(t)) / cos(t)
a = Line(O, B)
C = Point(Circle[O, r_1])
b = Segment(O, C)
d = Circle(O, C)
D, Q = Intersect(d, a)
e = Polar(Q, c)
P = Intersect(e, a)
