FunctionTrigonometryProbability & Statistics
This example demonstrates the solutions of randomly generated quadratic equations. Key mathematical concepts include quadratic equations and probability. Using GeoGebra commands such as RandomElement, Random, and Intersect, a dynamic quadratic equation solution graph is constructed. Suitable for high school math education and learning.

GeoGebra Commands & Parameters

  1. RandomElement({-5, -4, -3, -2, -1, 1, 2, 3, 4, 5}) → a
  2. RandomElement({-5, -4, -3, -2, -1, 1, 2, 3, 4, 5}) → c
  3. Random(-10, 10) → d
  4. Random(-20, 20) → b
  5. Textfield(m) → InputBox1
  6. Random(-10, 10) → p
  7. Intersect(f, k) → A, B
  8. OrthogonalLine(A, i) → g
  9. OrthogonalLine(B, i) → h
  10. TableText({{A1, B1}, {-3, f(-3)}, {-2, f(-2)}, {-1, f(-1)}, {0, f(0)}, {1, f(1)}, {2, f(2)}, {3, f(3)}}, "|_r") → text3
