Solve with integrating an implicit function

[Helge Gabert]

Alberto, you're very welcome - - but Valentin Albillo is the one who originally came up with the post a few years back - - I only dug it up and tried it on the Prime.

And yes, it is amazing how fast the implicit function plots in advanced graphing - - it would be interesting to know what algorithm is used - - it sure beats calling fsolve repeatedly! (It is also amazing to note how easy it is to program this problem on the 1980s era HP-71B (with the optional Math module plugged in, I assume).
