This tool allows the plotting of several functions simultaneously, navigates through them, and finds the critical points with several numerical methods. Depending on the problem the user can choose a context in two or three dimensions and can also select the more convenient method to solve a specific problem. Moreover, the parameters modification in a particular method is transparent and clear; the goal of this software is to simplify the work of students, engineers and researchers, working on a graphical and interactive environment, on a completely intuitive user interface.]]></p></abstract>
