GeoGebra Drawing Test

GeoGebra is a free mathematical drawing website with a cloud interface. After registration, users can use their creativity to use mathematical knowledge to design drawings or animations. Below is how I used my existing mathematical knowledge - conic sections, to move a 3D sphere around and create an animation. It took me a while to create a simple animation of the motion of the sphere. Those who are interested can also register themselves. Let’s play with an account.
