   The Graph of function

   Geometry, Figure

   A body of rotation

   Graphic (2D, 3D)

     -  ray trace



Science,  (parametric) expressions of functions

(Partial) differentiation (coefficient)

(indefinte) integral

in the range of complex numbers


Statistic Analysis


System Requirement Details

Over Pentium 300MHz (recommendation)

Windows 95/98/me/NT 4.0/2000/XP/Vista

16MB RAM (32MB or more: recommended)

Hard Disk Space 17MB (29MB)

CD-ROM Drive

VGA or over it

The underlined parts are added functions in comparison with version 3.0.


Drawing the graphs of all 2- or 3-dimensional functions (curves, surfaces) represented as positive, negative, and parametric functions in the rectangular, polar, sphere, and cylindrical coordinate systems by the input of formulas

   Curves also can be drawn like 3-dimensional figures. (the above pictures)


The figures that are difficult or impossible to represent with expressions can be drawn with the use of figure commands or figure tools. - All in 2D, 3D

 (Using figure tools, we can draw various figures of 2- or 3-dimensions including functions by use of the mouse only.)

(Although not knowing the syntax for commands, we can use it easily with the 'to input only information after selecting a command' dialogue box.)


It is possible to draw a transformed graph of the original graph by using the transformation function.


It is possible to easily draw a body of rotation by curves or lines only.

By using ray trace, it is possible to make the effects of transparence, reflection, and shadow.


(Partial) differentiation, (indefinite) integral, Calculation in the range of complex numbers,

    Matrix: convenience (including rational numbers)

   Science, (parametric) function, in the range of rational numbers (the result : as an irreducible fraction),

    calculation without regard to ciphers - decomposition to prime factors, +,-,*,/, sqr, nPr, nCr, nHr, n!

  - Trigonometric function, Inverse trigonometric function, Hyperbolic function, Inverse hyperbolic function, exponentional function, log,

    abs, sqr, int, conjugate complex number, sgn, etc. offered basically.


Statistic Analysis

   (linear regression analysis): to a sample having as many as 20 variables, which is possible to compute according to the appointed group.

    Class- or Apiece-classification, Frequency table, Graphs related to statistics

    Parameter estimation, hypothesis test, analysis of variance

    (Multi-) linear regression model, polynomial regression model, finding the best regression equation etc.

    Special calculation; sum, mean, standard deviation and order for rows or columns of data


 Others; Inputting coordinate values (automatically) and arrowheads,  Adjusting the size of the coordinates region (2D) 

   Managing drawn pictures; Viewing, modifying and saving drawn pictures and related information as pieces or as a group.

   Of course, it is possible to save only formulas. By opening it, it is possible to obtain the same result when all conditions are the same.

   Inputting characters and basic editing of pictures

   We can use the drawn graphs in other application program, such as 'word processor', 'paint-brush'.
