MathCalc run with the calculator and graph plotter mode. Within the calculator mode, you can compute mathematical expressions, trigonometric, hyperbolic or logarithmic functions. The entered expressions and functions are saved into formula lists. The program has a handy, easy-to-use formula editor for these lists. Within the plotter mode, you can plot 2D graphs a few ways: using tabular data, importing the data from files, pasting data from Windows clipboard or assigning Cartesian (y = f(x)), polar (r = f(u)) or parametric (x = f(u); y = f(u)) functions. It is possible to save, print and export graphs plotted. The program allows zooming and scrolling graphs. MathCalc supports adjusting of all chart elements in the real time mode (WYSIWYG - What You See Is What You Get). The graphs plotted, you can edit, save, print out and export to files of graphics formats (BMP, WMF or EMF). In addition, it is possible to export the graph points to a text file.
