Plotting a graph takes time. Often mathematicians just want to know the key features. These are: shape, location and some key points (such as where the graph crosses the axes or turning points).

Let user move the origin point of the graph freely (parametrization in relation of the origin point). Support to exponential function drawing. Improve the automatic selection of points for ...

In this paper the generating function for the numbers of variations with repetitions and a certain type of restrictions is determined. The variations in question are connected with paths in ...
