Ellipse Drawing Mechanism with 3 Sliders
Channel: Saltire Software
Date: 28/10/2020

This ellipse drawing mechanism is tricky to model in GXWeb, as the third slider cannot be constrained to lie on the y axis.  We have to approach the problem indirectly by finding an expression for its distance from the axis and solving.
We use Wolfram Alpha as our CAS to do the solution.
