This
version is run
in DOS. It can draw functions of the type of y=f(x), x=f(y),
x=f(z); y=f(z) (parametric
function),
r=f(z),
z=(angle) (polar coordinates system). It can draw a
graph
to transform the formula, trace
the coordinate value of the graph. It has the following
function; scientific
calculation, saving a picture to bmpfile, printing
in dos, adjusting
the increase of variable value of domain.
[Picture
collection
screen]
V1.0

here, being also possible
to draw a graph
V2.0[by visual basic]
The
function of this version
is similar to version 1.0. Saving a numerical formula. Printing. Other functions
are strengthened
and added. Adding more
convenient function in trace function
V2.0
 Opening
only picture files (to view graphs) and Printing  up to
35 numbers in the folder
V3.0
The size of the drawing screen and
the entire screen of this program are adjustable in any size. All
of Graph, Trace,
Transformation is upgraded to
3 dimensions.
The function of the picture collection
screen and other functions were
so strengthened that one can modify, apply
the picture later. And after drawing and editing, modifying the
picture, we
can save the picture
collectively or individually. We can use
it in studying, and edit simply, modify and apply pictures
easily. Adding more convenient function to use.
It
is possible to draw the graph of mathematical function at
will. In the function of calculation the results is
also displayed
as an irreducible
fraction. The function of calculation of rational number,
parametric multi variable function , and integral
were added. Also 'Help' function was added. It
is possible to input characters in the picture and
modify
it.
V3.0
 After
making a picture box, we can save a picture and characters of the
drawing
screen in the picture box. It is possible
to adjust the size of the picture box. In modifying mode
it is possible to modify items
inputted before. Being also possible to move the position
of the picture box. Being possible to copy and paste
only the picture in the picture box.
Being possible to make picture boxes up to
255 numbers. Being possible to save
and open the picture box collectively or
individually.
Demo
 Its function was restricted from v2.03. It was
restricted so that only the graph of rational, polynomial functions in the
type of y=f(x) may be drawn.
