MathCalc is a mathematical calculator as well as a 2D graph plotter. The program can work with two modes: the calculator and graph plotter mode.

You can calculate mathematical expressions, trigonometric, hyperbolic or logarithmic functions. For entering formulas, you can use as a keyboard as "floating" panels. MathCalc allows saving formulas in the Formula List in the form of "Formula Name = Formula". Working with the Formula List, you can use substitution variables (the characters from "A" to "Z") instead of numbers. Within the plotter mode, you can plot two-dimensional graphs of Cartesian (y = f(x)), polar (r = f(u)) or parametric (x = f(u); y = f(u)) functions. The program supports adjusting of all chart elements in the real time mode (WYSIWYG - What You See Is What You Get). The graphs plotted, you can scale, scroll, print out and export to common graphics formats (BMP, WMF or EMF). In addition, it is possible to export the graph points to a text file.
