I'm not sure if it fit here (if not, I'll delete the post), but basically, in France, for the baccalaurat, we need to prepare 2 presentations related to our specialities, mine are earth and life science and, well, mathematics. The problem is, I have my subject for science but I can't find anything for mathematics. I found some interesting studies, but it was too hard to explain, knowing that we haven't any other support than a white board. Plus, I don't understand if we need to make calculus or if explaining how stuff works is enough. I know there are some french people on the server, maybe there are teatchers or ex-student who got through this and know what's expected to do. It's a bit urgent, because at the 27th we will pass blank exam, and then our subject will be definitive. I had something but that didn't worked well, so I need to find something before next week.
I did my bac 6 years ago, that changed a lot
