MathGraph intended for research of functions of a kind y=f(x) also works in two directions: graphic constructions and mathematical calculations.
The program has an opportunity:

to find the roots of the equation f(x)=0 on the given interval
to build the graphics of the given functions
to find of an analytical type by derivative from the given function

to build the graphics of derivative functions
to build the graphics tangents and normals in points;
to calculate determined integral and variation of function

MathGraph can work with many functions simultaneously. At the large opportunities the program has the convenient and friendly interface.
Also are the parameters for adjustment of graphic area. You can save graphic area in an image file.
The program can demonstrate some methods of calculation that are used in MathGraph.

Working area of the main window of the program is possible to be broken on two parts.
On the right part is graphic area in which schedules of functions are under construction, schedules of derivative functions, tangents and normals.
On the left part is panel of functions wich consist of:

the panel of editing of function;
Here it is possible to add, destroy, edit mathematical functions, to set color and visibility of the schedule of each function.
the panel of viewing of functions; All functions entered by the user with parameters of display of the schedule here are displayed, and active function gets out.

the panel of calculations; Here it is possible to spend different calculations and additional constructions for active function. And here are located such pages: roots, integral, a derivative and tangents, a variation, values of function.
the panel of viewing mathematical type of function and derivative; This kind of functions can be kept in a graphic file with the help of the contextual menu.
