Sagemath, as an alternative of Geogebra
I was looking for an alternative of Geogebra - http://www.geogebra.org (since it's no longer available for my GNU/Linux distro), then I came across SageMath. My question is, is it possible to use SageMath as a complete alternative of Geogebra? Or there are other good alternative available for Geogebra than SageMath; if so, could you suggest it to me?
No, it is not possible. The capabilities of geogebra are unique, there is no software known to me with the functionalities of geogebra. Note that sage is a CAS, however geogebra is an app about geometric constructions, they are designed for different purposes and have a very different use. Your question is similar to ask if you can use a hammer as a substitute of a spoon to eat.
Very often i also want to have only a final picture for a geometric setting (done in geogebra). Unfortunately, i always have to do a lot of work to get some picture from sage, which is suitable for a LaTeX-insert. Each time i do this, i promise to me to write next time a raw package... (Because it is rather easy.) The main problem is the choice of an open source (main stream) package allowing an "adapter" (from python or java or C++ or whatever) to it as input, and so that the output is in all / most formats we need, e.g. html, java, latex, (raw text = ascii art)... As i have it in memory, geogebra refused at request to offer such a bridge for sage. If somebody names me such a package, i will start working (and ETC will be also inside), although i'm with job (time) outside mathematics.
