Re: Isoperimetric Cordiform

Like you, I thought there should be a closed-form representation, but wasn’t able to find it. However, I did not study the solution exhaustively. The Geocart calculation is numerical and relies on caching and interpolation for speed. Otherwise, it would be quite slow. Thank you for your quick answe...

Hello, everyone. I decided to derive the equations of the Isoperimetric Cordiform projection for the challenge, but I stucked and it is very frustrating. Based on its only property "Correct along all parallels and meridians in the default aspect." I have written the next equations for the ...
