"Riemann Sphere" for asymptotic graphs
Stereographic projection of the plane onto a sphere.
This can be an excellent activity to deepen understanding of asymptotes.
Draw these graphs on balloons!
Lesson idea
- Start with three points defining a circle from my other geogebra file.
- Use this file to introduce idea of sketching graphs with asymptotes.
- Draw the graphs on balloons!
