    MathCalc 2.0
    ==========================================
    MathCalc is a handy mathematical calculator as well
    as easy-to-use 2D graph plotter. The program has a
    friendly user interface, easy to learn and
    comfortable to operate. MathCalc can work with two
    modes: the calculator mode and the graph plotter mode.

    Within the calculator mode, you can calculate
    mathematical expressions, trigonometric, hyperbolic or
    logarithmic functions.
    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.

    Software and Hardware Requirements
    ==========================================
    1) PC with a Pentium 200 MHz processor or higher;
    2) Microsoft Windows 98/ME/2000/XP;
    3) 32 Mb of RAM or more;
    4) 2 Mb free hard disk space.

    Installing
    ==========================================

    Main Characteristics MathCalc
    ==========================================
    MathCalc can work within two modes: the calculator mode
    and the graph plotter mode.

    The program supports following features at the calculator
    mode:

    - a calculation of trigonometric, hyperbolic and
      logarithmic functions as well as standard mathematical
      operations;

    - possibility to enter mathematical formulas as with a
      keyboard as with buttons of floating panels;

    - saving of entry expressions in Formula List in the
      form of "Formula Name"="Formula";

    - it is possible to type a function as lower-case as
      upper-case characters (Exp[2], LN[3], ln[3]);

    Within the graph plotter mode, MathCalc support the same
    features as at the calculator mode and in addition:

    - assign functions at Cartesian (y = f(x)) or polar
      (r = f(u)) coordinate frame. It is also allowed setting
      graph functions as parametric ones (x = f(u); y = f(u));

    - possibility to export charts into files of graphics
      formats (BMP, EMF, WMF) as well as to the MPC file
      format. MyPlot Chart Editor operates with MPC format.
      This program is specially intended for editing of
      various types of charts;

    - exporting a data table to text file;

    - copying into the Windows clipboard as BMP, EMF, WMF
      formats;

    - customizable printing of charts;

    - scaling of charts;

    - setup of all chart elements in the real time mode
      (WYSIWYG - What You See Is What You Get);

    - use of "linked" windows for the convenience of the
      adjustment of chart elements;

    - multilingual interface support.
