This example demonstrates how to find the magnitude of a vector using GeoGebra. Key mathematical concepts include the length and direction of vectors. Commands used include Intersect, Vector, Dilate, Midpoint, If, Angle. Suitable for students in middle school and above to learn basic vector concepts.

GeoGebra Commands & Parameters

  1. Intersect(eq2, g) → E
  2. Vector(A, B) → u
  3. Intersect(f, eq1) → C
  4. Dilate(E, If[2 < a ≤ 3, 3 - a, 0], B) → C'
  5. Dilate(A, If[1 < a ≤ 2, 2 - a, 0], E) → A'
  6. Vector(A, A') → v
  7. Midpoint(A, B) → D
  8. Vector(E, C') → w
  9. If(y(E) < y(A), "south", y(E) > y(A), "north") → text10
  10. If(x(B) < x(A), "west", x(B) > x(A), "east") → text12
  11. Angle(B, E, A) → α

AI Drawing Prompt Reference

Draw a vector showing its magnitude and direction. First, find the intersection of two lines, then draw a vector from the starting point to the intersection. Next, scale this vector based on conditions, find the midpoint and another intersection point. Finally, label the direction (south or north) and horizontal direction (east or west) of the vector, and calculate the angle between the vector and the horizontal line.
