Dear All,(adsbygoogle = window.adsbygoogle || []).push({});

I am trying do find the minimal surface of revolution between two coaxial circular rings of DIFFERENT diameter.

I could not find it solved in the net. So I tried to solve numerically system (13-14) Minimal Surface of Revolution -- from Wolfram MathWorld

to determine "a" and "b" for given coordinates did not work I got complex solutions...

If anyone knows where I can find the solution of this problem or if anyone can give more info on this will be grate.

Thanks.
