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.
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.
@ColinTheMathmo Something like this?
@rnather That's one of the things I was looking for, thanks. If I can find a clean narrative I'd like to use that, so how would you like to be credited? Name? Handle? Link? See here for examples:
@ColinTheMathmo Oh, 'twas my pleasure. Quite literally, as your diagram provided me with an incentive to figure out how to use cairo from Haskell.
