This program displays graphs of 2D and 3D functions and solves equations. 2D graphs features up to two functions displayed at one time. On the same screen, integral, and derivative curves for the main function can be displayed as well. Extreme values of functions can be found. Indefinite areas can be marked. Also, the program calculates Y value for a given X and all X values for a given Y. Maximal effort has been made to make all calculations and drawings efficient, as well as precise (e.g., functions like tan(x) are drawn with all points that fit on the screen and without extra lines). Graphs can be viewed with user defined light and surface settings, like direction of light vector, fog intensity, ambient light intensity and degree of specular reflection. They can be rotated to any position. Preview for light settings and rotation is available. Version 2.5 may include unspecified updates, enhancements, or bug fixes.
