    Two ellipses rotate within a third such that the two smaller ellipses are always tangent to each other and the larger ellipse. Adjusting the variable X demonstrates this rotation. All three ellipses are constrained only by their implicit equations, and the moving ellipses’ equations include functions of X that allow them to rotate. Can you figure out what the equations are (the other constants i…
