Implicit curves
Answered
In GeoGebra beta it's now possible to have implicit curves like
a: sin(x) + sin(y) = 1
Known bugs:
* the drawing algorithm is very simple and fails in some cases
* for independent curves, file sav + open does not work (fixed for next release)
Planned features:
* Point on curve
* Transforms: translate / dilate / rotate ...
* Commands: Tangent, Intersect, Curvature, CurvatureVector, ImplicitDerivative
In case you have some curves you think are important to work nicely, please list them in this topic.

Very nice.
Rather than specifying curves, I would love to be able to calculate extreme points, even if this means bad precision  both for implicit curve and for loci. In modelling you often have a geometrical model in one window, investigate how one value depend on an other in another window, produce a locus to illustrate this and then you want to find a maximum of the locus. Which is currently not possible. Workarounds involve a cubmersom process of putting points on the locus and fitting a polynomial to these points. I realize that a locus has low precision but surely it must still be possible to find a maximum in some sense?
The same goes for implicit functions. Drawing them are nice, investigating them even better.
Hi,
thank you for this nice news.
Please : implicit function with exp(...)
@Patrick: what implicit function with exp(...) do you mean exactly?
@themadmathematician some progress for the next release

Is this supposed to work in the desktopversion yet?
Regards
Mikkel
