GeoGebra 命令及参数

1. Line(P, Q) → l_c
2. If(FractionText[Slope[l_c]] ≟ "?", "undefined", FractionText[Slope[l_c]]) → actualgradient
3. Random(-6, 6) → c
4. Random(0, 6) → a
5. If(gradient_{answer} ≟ Slope[l_c], true, If[gradient_{textanswer} ≟ actualgradient, true, false]) → AnswerCorrect
6. Function((0 * x) - 1, -3, 3) → f
7. Textfield(gradient_{answer}) → inputBox1
8. Vector(Q, N) → vectorhorizontalrun
9. Vector(N, P) → vectorverticalrun
10. Midpoint(N, P) → M_{NP}
11. Midpoint(N, Q) → M_{NQ}
12. Text(horizontalrun) → texthorizontalrun
13. Text(verticalrun) → textverticalrun
14. Function(cos(x) + 2, 0, 31.416) → f_{racepath}
15. Integral(f_{racepath}, 0, 31.416) → wavebody
16. Corner(2, 4) → A
17. Textfield(gradient_{textanswer}) → inputBox2
18. Function(((-(x(l_c) / y(l_c))) * x) - z(l_c) / y(l_c), -8, 10) → f_{line}
