The path the point follows describes an ellipse.
Notice the equation is the equation of an ellipse.

I can't seem to get this question...:
A ladder of length L standing on level ground is leaning against a vertical wall. The base of the ladder begins to slide away from the wall. What is the equation of the path followed by any point of the ladder? (Hint: let the distance from the top of the ladder to the point in question be K).
The answer is x^2/K^2 + y^2/(L-K)^2=1
...how?!
Thanks for your help
