Nigma learned to draw graphics
Now Nigma draws beautiful graphs of functions and even conducts their research .

When examining Nigma function
- finds the range of valid values;
- finds the intersection with the axes of abscissas and ordinates;
- checks the function for parity / oddness;
- checks for periodicity and finds a period;
- finds limits at the points of discontinuity of the function, limits to the left and right at the point, the behavior of the function at infinity, and the inclined asymptotes of the function;
- calculates the derivative, the roots of the derivative, the intervals of increase / decrease of the function;
- Finds global maximum / minimum functions;
- builds a schedule;
A significant difference from Western counterparts is the fact that Nigma builds graphs based on data obtained in the study of the function.
In this case, the graphs can show the break points and asymptotes.
For example, compare the graph y = sin (x) / x for nigma and tungsten .
Victor Lavrenko, head of the Nigma.ru development team: “Today we launched the beta version, but by September we plan to make the study of functions more detailed, to embed three-dimensional graphs and graphs for parametric functions, implicitly defined functions, graphical solution of inequalities and systems of equations. New features will be useful not only for schoolchildren, but also for students of technical specialties. ”
The mathematical system Nigma.ru was launched in October 2008.
Then the developers taught the system to solve equations and systems of equations, simplify expressions, solve problems using thousands of different quantities and constants, etc.
Since the launch of Nigma, mathematics has been constantly evolving: the developers have added a solution path for equations and to simplify expressions , as well as improved the user request recognition system.
In December 2009, the solution to problems was added to the already existing wide list of possibilities , for which it is necessary to determine the range of permissible values (ODZ), the calculation of integrals and derivatives .
