Math software users must know the features of different math software like Maple, GeoGebra, Matlab. Comparing Maple and GeoGebra software (also considering other math software) one can see the differences regarding the commands, tools, the help files, the syntax used and the possibilities of caring out a task. Also, we see that there are tasks that can be carried out using Maple but not with GeoGebra and Matlab, and they must be easily adopted to each one of them. We try to make use of some commands and techniques of Maple for GeoGebra in completing the already existing summary help files in order to have a set of instructions for the teachers and the students who use GeoGebra, meeting this way some of the most necessary needs of them in using GeoGebra tools and commands for doing work. Keywords: Math software; dynamical Geometry program; GeoGebra; computer Algebra system 1. Introduction While using Maple in CEEPUS Summer university in Miskolc we found extremely useful the help files of that software. Our suggestion is that math software users must know these two useful software, others also, and they must be easily adopted to each one of them. We try to put together something similar for GeoGebra in completing the already existing summary help files, specially for constructing graphs, in order to have a set of instructions for the teachers and the students who use GeoGebra, meeting this way some of the most necessary needs of them in using GeoGebra tools and commands for doing work. 2. Considerations regarding the plotting 2.1. Maple With Maple can be plotted graphs of functions putting conditions on their domain and range, on the graphs colours etc. There are different options of plotting: 1. No boundaries on function domain. The syntax and commands are: < Plot(sin(t),t); < Plot(3/x,x), ..... 2. Boundaries on function domain and range: < Plot(sin(t),t=-Pi..Pi); < Plot(sin(x)+cos(x),x=0..Pi); < Plot(tan(x),x=-2*Pi..2*Pi,y=-4..4); < Plot(sin(x),x=0..infinity); ..... 3. Several graphs on a pad and different graphic colours (multiple plots): 1 University of Miskolc, Hungary; e-mail: pkortesi@gmail.com 2 Department of Mathematics and Informatics, University “Aleksander Xhuvani”, Elbasan, Albania; e-mail: pkallogjeri@gmail.com
