This example demonstrates how to calculate the direction cosine with the x-axis using vectors and angles. Key mathematical concepts include direction cosine and vectors. It utilizes Vector, Point, and Angle commands in GeoGebra. Suitable for high school and above students learning coordinate geometry and trigonometry.

GeoGebra Commands & Parameters

  1. Vector(O, P) → u
  2. Point(xAxis) → A
  3. Point(yAxis) → B
  4. Point(zAxis) → C
  5. Angle(A, O, P) → α
  6. Angle(B, O, P) → β
  7. Angle(C, O, P) → γ
