Birgit Lachner :verified: 📯<p><span class="h-card" translate="no"><a href="https://bildung.social/@w" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>w</span></a></span> Mit was hast du das dargestellt? Vermutlich <a href="https://bildung.social/tags/JSXGraph" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>JSXGraph</span></a> </p><p>Sieht ja an sich gut aus, aber mit <a href="https://bildung.social/tags/GeoGebra" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>GeoGebra</span></a> wäre das vermutlich schneller gelöst? Einbetten geht auch und einen Knopf zum Abspeichern als Bild kann man auch haben. Lässt sich dann nachträglich auch besser bearbeiten vermute ich.</p><p>Okay, was die KI betrifft, da weiß ich nicht, ob die bei GeoGebra helfen kann.</p><p>Wenn du Fragen hast zu einer konkreten GeoGebra-Zeichnung kannst du gerne nachfragen.</p>
Marcus Green<p>Yesterday was day 1 of the 3 day International Meeting of the STACK community. </p><p>It was inspiring to be around so many smart people working on improving <a href="https://fosstodon.org/tags/maths" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>maths</span></a> education.

Christian Lawson-Perfect<p>There's a new release of <a href="https://mathstodon.xyz/tags/JSXGraph" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>JSXGraph</span></a> - <a href="https://jsxgraph.org/wp/2024-01-26-release-of-version-1.7.0/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">jsxgraph.org/wp/2024-01-26-rel</span><span class="invisible">ease-of-version-1.7.0/</span></a>.<br>Among other things, it adds an 'implicit curve' object.</p><p>I thought I'd try it out in <span class="h-card" translate="no"><a href="https://mathstodon.xyz/@numbas" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>numbas</span></a></span>, then realised that the way Numbas evaluates expressions is far too slow for this kind of numerical approximation - it does a lot of dynamic type-checking that takes a long time.</p><p>So I nerdsniped myself into writing a routine to take a Numbas JME expression and make a function which is as close to native JS as I can get. It works on all of the operations that you'd expect a student to use, since those have plain-JS implementations. There's just the control flow stuff and things to do with collections that need the whole JME system.</p><p>And now that I've done that, I have a nice, real-time interactive function plotter! <br>I've made a demo question at <a href="https://numbas.mathcentre.ac.uk/question/152679/give-a-function-defining-an-implicit-curve/preview/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">numbas.mathcentre.ac.uk/questi</span><span class="invisible">on/152679/give-a-function-defining-an-implicit-curve/preview/</span></a></p><p>It's really simple to implement in Numbas: you set up a JSXGraph diagram, and fill in the function parameter of the implicit curve object with the expression the student typed. Just a few lines of code. Nice!</p>
