GeoGebra Commands & Parameters

  1. Point(f) → A
  2. Tangent(A, f) → a
  3. OrthogonalLine(A, a) → b
  4. Intersect(b, yAxis) → B
  5. Vector(B, C) → u
  6. Vector(A, C) → v

AI Drawing Prompt Reference

Draw a parabola and select a point A on it. Draw the tangent line a at point A, then draw the orthogonal line b to line a. Find the intersection B of line b and the y-axis. Draw vector u from B to point C and vector v from A to C, illustrating the relationship between the parabola, tangent, orthogonal line, and vectors.
