The Sum of Two Counter-Rotating Circular Vectors Is an Ellipse

Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
The two vectors and their sum are shown as black, blue, and red, respectively. You can change the size of the blue vector relative to the black vector; both vectors rotate at the same rate but in opposite directions.
