{Making math textbooks and materials with \TeX+\acro{KET}pic+hyperlink}
{Yoshifumi Maeda and Masataka Kaneko}
{Because of its precision and simplicity, the graphics capability
originally present in \TeX\ should have great potential in mathematics
education.  However, it seems to be burdensome for usual \TeX\ users to
fully utilize such capability.  Although including the graphical images
generated by using computer algebra systems (\acro{CAS}) is a typical
alternate approach, the resulting documents tend to become inefficient
for actual use in classroom.

The \acro{CAS} macro package named \acro{KET}pic is one of the most
hopeful candidates for realizing handy and efficient use of \TeX\
graphics.  For instance, it enables us to edit high-quality math
textbooks and materials containing

\myitem 2D-graphics which are precise in shape and length
as in Sample 1, and
\myitem 3D-graphics which are readily understandable
as in Sample 2.

In this talk, it is emphasized that the programmability of \acro{KET}pic
(associated with \acro{CAS}) and \TeX\ could make the use of \TeX\ more
flexible.  For example, in Sample 3,

\myitem many documents with graphics can be readily generated
by using both for-loop programming
and ``meta commands'' of \acro{KET}pic, and
\myitem those documents can be readily linked
also by using ``hyperref''' package of \TeX
(connected to ``hypertextlink'' function).

Such unified use of \TeX\ graphics and \TeX\ programming through
\acro{KET}pic might be applicable to many other situations in math
classrooms, and should enhance the possibility of \TeX\ use in
education.
