GeoGebra 命令及参数

1. Integral(acceleration) → velocity
2. Polygon(A, B, 4) → poly1, b_1, c, d, e, C, D
3. Integral(velocity_m) → distance_m
4. Polygon(A', B', C', D') → poly2, a', b', c', d'
5. Intersect(distance_m, b', 1) → M
6. Polygon(A', C'', B') → poly3, k, l, m
7. Segment(B', M) → b
8. Point(b) → E
9. OrthogonalLine(E, xAxis) → g
10. OrthogonalLine(E, g) → h
11. Circle(E, b) → p
12. Intersect(p, g) → F, G
13. OrthogonalLine(G, g) → i
14. Intersect(i, yAxis) → H
15. Intersect(h, yAxis) → I
16. Polygon(I, E, G, H) → poly4, i_1, e_1, g_1, h_1
