絕對值不等式(2)

b = 2 (slider from 1 to 5, step 1)
F: (x(Corner[1.0]), 0.0)
a_1: y(Corner[3.0] - Corner[2.0])
a_2: a_1 / 20.0
H: F + (0.0, a_2)
a = -5 (slider from -10 to 10, step 1)
A: (a, 0.0)
C: A - (b, 0.0)
D: C + (0.0, a_2)
B: A + (b, 0.0)
E: B + (0.0, a_2)
多邊形1, c, d, e, f = Polygon(F, C, D, H)
G: (x(Corner[2.0]), 0.0)
I: G + (0.0, a_2)
多邊形2, b_1, g, i, e_1 = Polygon(B, G, I, E)
v = Vector(E, I)
K_1: (x(Corner[1.0]), 0.0)
K_2: (x(Corner[2.0]), 0.0)
u = Vector(K_1, K_2)
文字1: "|x" + (If[a > 0.0, "-", "+"]) + (abs(a)) + "|≥" + b
D_q: K_1 + (0.0, a_2)
w = Vector(D, D_q)
