Rinne aus drei Brettern

Für welche Stellung fasst die Rinne

am meisten Wasser?

Ha 01 bzw 06

fak = 0.25
a = 4
A = Point(xAxis)
c = Circle(A, a)
C, D = Intersect(c, xAxis)
m = LineBisector(A, D)
B = Point(c)
b: x(A) - x(B)
E = Mirror(B, m)
P, d_1, a_1, d, e = Polygon(B, A, D, E)
f: 1.0 x = b
V: (b, P * fak)
F: (a + b) * sqrt(a^(2.0) - b^(2.0))
g(x) = (a + x) * sqrt(a^(2.0) - x^(2.0)) * fak
k(x) = g(x)^(2.0) * fak
H: (x(B), 0.0)
h = Segment(B, H)
s_b = Segment(H, A)
X: (b, 0.0)
O = (0, 0)
i = Segment(O, X)
