MultyGraphix is the calculation software for technical professionals, educators, and students. It's help you to see the relation and graphic form of your formulas. Some of it's features include easy to use MDI interface, unlimited functions in the same window, integration, derivation, root searching and value evaluation. It allows you to plot 2D explicit and parametric functions in the cartesian and polar coordinate systems, to plot 3D explicit and parametric functions in the cartesian, cylindrical and spherical coordinate systems. It also allows to expect certain integrals f(x)dx to find roots of the equations f(x) on the certain interval a numerical method.
