its freeware both of them. Graphmatica is not limited in any way, however the author would like a registration, but you dont have to. Geogebra is 100% freeware. What about examining the software before writing unusefull comments?

The second one (Graphmatica) i much better and powerful.
Should be good if it allowed 3D and matrix operations
well. Geogebra allows cirkles and that stuff, and it can easly find tangents and degrees and that stuff to them, where graphmatica can only work with parables and such functions.
