Line Integral is a simple mathematical utility, totally free and that runs under MSDOS environment, which will allow you to represent different types of graphic functions.
The graphical functions that Line Integral allows to represent are of the type y = f (x), x = g (y) and polar equations of the type r = r (t), where t is the angle, as well as parametric equations of the type x = x (t) or y = y (t).
Up to a total of nine equations can be represented. Line Integral also calculates the integrals over the curves. Although it runs under the MSDOS environment, you can also use the mouse to access the different sections of the program.
You can free download Line Integral 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
