The
current version
$wims_version of wims has several applications which
demonstrates
(non
-exhaustively
) what one can
do with a wims
system.
<ul>
<li>Take a look at the
!href target=wims_demo module=tool/geometry/animtrace&cmd=intro animated plotter
$(): it allows you to plot curves and surfaces with zooming, deforming and rotating
effects, more easily as you may possibly imagine.
</li><li>The game
!href target=wims_demo module=U2/algebra/qpuzzle Q-Puzzle
gives a very good idea of how wims can provide a convenient way to combine
multimedia means and abstract mathematical notions.
</li><li>The game-exercise
!href target=wims_demo module=H6/geometry/coincfree Coincidence-freehand
shows the possibility to create interactive graphic exercises of a new
style.
</li><li>The exercise
!href target=wims_demo module=U1/algebra/corresjs Correspondance
gives an idea of the possibility of embedding javascript interactivity
into a wims application.
</li><li>The exercise
!href target=wims_demo module=U1/algebra/accordance Accordance
shows the possibility of linking different wims applications:
except for the easiest level,
such an exercise is practical only if the user can use computer to
solve a linear
system. Now such a solver
(another wims application
) is available directly in the
exercise page
, via a hypertext
link. In order to teach the student to
choose the appropriate tool, some irrelevant links are also added. <br/>
Please notice that the lack of direct data communication between the two
modules is only a choice of the design of the module, in order to make
the student type the matrices.
</li><li>The tool
!href target=wims_demo module=tool/analysis/function Function
illustrates the possibility to create pages which are at the same
time powerful and easy to use. By linking a plotter (gnuplot), a symbolic
calculator (Maxima) and a numerical calculator
(pari) at backend level, it allows the user to click on a root (or a
local extremum) he sees on the curve, and get the value of the root (or
local extremum) at arbitrary precision. <br/>
To achieve this, softwares are dynamically called at backend. First,
gnuplot is used to draw the curve in the given interval. When the user
clicks on a point, gp is called to try to find a root in the neighborhood
of the point. If it fails, Maxima is called to compute the formal
derivative of the function, and gp is called again to find a root of the
derivative in the neighborhood (which will be the local extremum).
</li><li>This document itself is an illustration to the fact that wims can
provide an easy way to dynamically reorganise contents of a document. By
changing a parameter
, contents of the document can be grouped
, split, or
chosen, in various ways. (Remark that this document is itself a wims module.)
