This example illustrates the concept of irrational numbers, which are real numbers that cannot be expressed as a ratio of two integers, such as the square root of 2 and pi. Using commands like Point, Intersect, and UnitVector, a geometric figure with irrational number properties is created. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Point(yAxis) → C
  2. Intersect(f, xAxis, 1) → R1
  3. Intersect(f, xAxis, 2) → R2
  4. UnitVector(a) → u1
  5. UnitVector(b) → u2

AI Drawing Prompt Reference

Create a coordinate plane with a y-axis. Plot (or assume) a curve f and determine its intersections with the x-axis at the positions corresponding to 1 and 2, marking the two intersection points. Then construct unit vectors based on the given vectors a and b, showing these unit vectors in the same plane. Arrange the scene so the y-axis, the curve f, the two x-axis intersection points, and the two unit vectors are all visible together, built in the order of first setting the axes and intersections, then adding the unit vectors.
