正弦函數的伸縮與平移

a = 2.2 (slider from 0.1 to 10, step 0.1)
b = 0.44 (slider from 0.1 to 5, step 0.01)
c = 0.6 (slider from -5 to 5, step 0.2)
f(x) = a * sin(b * x) + c
文字1: "f(x)=" + a + "sin(" + b + "x)" + (If[c < 0.0, "-", "+"]) + (abs(c))
u = Vector((x(Corner[1.0]), 0.0), (x(Corner[3.0]), 0.0))
v = Vector((0.0, y(Corner[1.0])), (0.0, y(Corner[3.0])))
