分段线性函数解读

GeoGebra 命令及参数

1. Sequence((n, f(n)), n, 0, t_1) → list1
2. Sequence((n, g(n)), n, 0, t_1) → list2
3. Segment((-1.9, 0), (-1.1, 0)) → line_0
4. Sequence(i - 0.4 < x < i + 0.4, i, 0, t_1) → photo_{road}
5. Sequence(x = i - 0.4, i, 0, t_1) → left_{road}
6. Sequence(x = i + 0.4, i, 0, t_1) → right_{road}
7. Sequence(x = i, i, 0, t_1) → mid_{road}
8. Sequence(Translate[truck_p, Vector[(0, f(0)), (i, f(i))]], i, 0, t_1) → photo_b
9. Sequence(Translate[bike_p, Vector[(0, g(0)), (i - g_y(i), g(i))]], i, 0, t_1) → photo_r
10. Segment((-1.9, 200), (-1.1, 200)) → line_{200}
