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

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.

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