It plots the function on the graphs between a maximum or a minimum limit, the derivates of function, up to the second one, and its integral, between an interval. There are also some tools like the calculator, which helps to solve formulas, the plot area, which permits to plot the area of a graph, and the finding of maximum and minimum in the function. You can colorize the graphs, zoom in or out the plane and export it as image to an external file.



KGeography allows you to open world maps and explore them. You can see the regions which form them and also you can obtain information about the capitals and flags. In the sidebar there are various buttons that offer test about various subject like capitals or to place the right region in proper space.


KTurtle is an education programming environment that aims to make learning how to program as easy as possible.
