Yes, the ellipse is positioned with its centre at (0,w). That's a nice way to express it in terms of just r, a and b. :)

Thank you Filip for your help. I've found a solution to this problem now which was given to me by someone on mathnerds.org, who suggested equating gradients - ie the gradient of the circle and the gradient of the ellipse are the same at the point they touch, so by differentiating and equating...

Filip - I'm not quite sure what I'm looking at there - is the first result the x value of the intersect point? I'm afraid this is going a little over my head.

Thanks Filip. I've given that a try and it has produced some solutions which I will now try integrating into my code. I didn't expect this to get quite so complicated!

Thanks morphism. Wow, that looks pretty nasty! I am downloading the trial of Mathematica, so I'll see if can give me the solutions to that. If it can't, then I guess I'm really stuck.

Hi everyone. I hope I've found the right place for my first post here. I have a geometry problem which I need to solve for a piece of software I'm writing, and I'm hoping someone might be able to help me. I have a non-rotated ellipse inside a circle, as in this diagram. I know the x and y...
