Subversion Repositories wimsdev

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.)
