Nigma learned to draw graphics

Not all chemists have beautiful formulas to paint, and the holiday has come for mathematicians.
Now Nigma draws beautiful graphics of functions and even conducts their research .

Investigating Nigma Function

1. finds the range of valid values;
2. finds the intersection with the axes of the abscissa and ordinate;
3. checks the function for evenness / oddness;
4. checks for periodicity and finds the period;
5. finds the limits at the points of discontinuity of the function, the limits on the left and right at the point, the behavior of the function at infinity, and the oblique asymptotes of the function;
6. calculates the derivative, derivative roots, intervals of increasing / decreasing function;
7. finds the global maximum / minimum function;
8. builds a schedule;

A significant difference from Western analogues is the fact that Nigma builds graphs based on the data obtained in the study of the function.
In this case, the graphs can show break points and asymptotes.
Let's compare, for example, the graph y = sin (x) / x of 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, embed three-dimensional graphs and graphs for parametric functions, implicitly defined functions, graphic solution of inequalities and systems of equations. New functions 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 its launch, Nigma-Mathematics has been constantly evolving: developers have added solution flow for equations and to simplify expressions , and have also improved the user's query recognition system.
In December 2009, the solution of problems was added to the already existing wide list of possibilities , for which it is necessary to determine the range of allowable values ​​(LDL), the calculation of integrals and derivatives .
