A request for those into both maths and technology - I need a diagram with an ellipse & a circle, each of the same area, the circle centred on one of the foci, & the ellipse a little eccentric, but enough to be clearly different from the circle.

Help??

I can draw an ellipse, & I can probably work out where the foci are, but getting them honestly of equal area is trickier. Ideally a diagram showing a family of ellipses of equal area, sharing a focus, including the circle, would *also* be good.

Oh, full name is sufficient: Rüdiger Nather. Anything else you'd like/need?

ColinTheMathmo@ColinTheMathmo@mathstodon.xyz@rnather Not at the moment - thanks. There have been some issues spotted with my explanations, so I may be a few days getting it sorted. If there is anything I'll let you know.

And thanks again.
