絕對值不等式(1)

a = 1 (slider from -5 to 5, step 1)
b = 4 (slider from 1 to 5, step 1)
A: (a, 0.0)
a_1: y(Corner[3.0] - Corner[2.0])
a_2: a_1 / 20.0
B: A + (b, 0.0)
C: A - (b, 0.0)
D: C + (0.0, a_2)
E: B + (0.0, a_2)
多邊形1, b_1, c, d, e = Polygon(B, C, D, E)
文字1: "|x" + (If[a > 0.0, "-", "+"]) + (abs(a)) + "|≤" + b
K_1: (x(Corner[1.0]), 0.0)
K_2: (x(Corner[2.0]), 0.0)
u = Vector(K_1, K_2)
