2 | The current version $wims_version of wims has several applications which |
||
3 | demonstrates (non-exhaustively) what one can do with a wims system. |
||
4 | |||
5 | <ul> |
||
6 | <li>Take a look at the |
||
7 | !href target=wims_demo module=tool/geometry/animtrace&cmd=intro animated plotter |
||
9291 | obado | 8 | $(): it allows you to plot curves and surfaces with zooming, deforming and rotating |
9 | effects, more easily as you may possibly imagine. |
||
5920 | bpr | 10 | </li><li>The game |
32 | reyssat | 11 | !href target=wims_demo module=U2/algebra/qpuzzle Q-Puzzle |
9291 | obado | 12 | gives a very good idea of how wims can provide a convenient way to combine |
32 | reyssat | 13 | multimedia means and abstract mathematical notions. |
5920 | bpr | 14 | </li><li>The game-exercise |
32 | reyssat | 15 | !href target=wims_demo module=H6/geometry/coincfree Coincidence-freehand |
16 | shows the possibility to create interactive graphic exercises of a new |
||
17 | style. |
||
5920 | bpr | 18 | </li><li>The exercise |
32 | reyssat | 19 | !href target=wims_demo module=U1/algebra/corresjs Correspondance |
20 | gives an idea of the possibility of embedding javascript interactivity |
||
21 | into a wims application. |
||
5920 | bpr | 22 | </li><li>The exercise |
32 | reyssat | 23 | !href target=wims_demo module=U1/algebra/accordance Accordance |
24 | shows the possibility of linking different wims applications: |
||
25 | except for the easiest level, |
||
9291 | obado | 26 | such an exercise is practical only if the user can use computer to |
32 | reyssat | 27 | solve a linear system. Now such a solver (another wims application) |
28 | is available directly in the |
||
29 | exercise page, via a hypertext link. In order to teach the student to |
||
17228 | bpr | 30 | choose the appropriate tool, some irrelevant links are also added. <br> |
32 | reyssat | 31 | Please notice that the lack of direct data communication between the two |
32 | modules is only a choice of the design of the module, in order to make |
||
33 | the student type the matrices. |
||
5920 | bpr | 34 | </li><li>The tool |
32 | reyssat | 35 | !href target=wims_demo module=tool/analysis/function Function |
36 | illustrates the possibility to create pages which are at the same time |
||
37 | powerful and easy to use. By linking a plotter (gnuplot), a symbolic |
||
38 | calculator (Maxima) and a numerical calculator |
||
39 | (pari) at backend level, it allows the user to click on a root (or a |
||
40 | local extremum) he sees on the curve, and get the value of the root (or |
||
17228 | bpr | 41 | local extremum) at arbitrary precision. <br> |
32 | reyssat | 42 | To achieve this, softwares are dynamically called at backend. First, |
43 | gnuplot is used to draw the curve in the given interval. When the user |
||
44 | clicks on a point, gp is called to try to find a root in the neighborhood |
||
45 | of the point. If it fails, Maxima is called to compute the formal |
||
46 | derivative of the function, and gp is called again to find a root of the |
||
47 | derivative in the neighborhood (which will be the local extremum). |
||
5920 | bpr | 48 | </li><li>This document itself is an illustration to the fact that wims can |
32 | reyssat | 49 | provide an easy way to dynamically reorganise contents of a document. By |
50 | changing a parameter, contents of the document can be grouped, split, or |
||
51 | chosen, in various ways. (Remark that this document is itself a wims module.) |
