GeoGebra ELLIPSE Activity
The graph below is that of x^2/a^2 + y^2/b^2 = 1. You are going to explore the effect of "a" and "b" by adjusting the sliders.
- What does increasing / decreasing "a" do to the shape of the graph?
- What does increasing / decreasing "b" do to the shape of the graph?
- What happens when a = b?
- Set a=3. How can we identify that value of "3" by studying the graph?
