The Dassault Mirage III G, G4, G8 and G8A are very interesting aircrafts tht deserve to be added to the french tech tree (repost because of insufficient info)

Pretty self explanatory, but the Dassault G series is a very interesting family of aircraft that could add diversity and originality to the French tech tree.

The line could start with the Mirage III G → Mirage G4 → Mirage G8 → G8A (fixed wing)

The Mirage G was France’s first variable-sweep aircraft, derived from the Mirage F2, and could exceed Mach 2 during testing. The G4 was redesigned as a twin-engine, two-seat aircraft intended for reconnaissance, strike and electronic warfare, while the G8 became a twin-engine interceptor. The G8 02 even reached Mach 2.34 during testing for an extended period of time with one of the engines on reduced after-burning mode at 12400m

An event vehicle, the LTV V-507, could also become an event aircraft for the USA. Although it never flew, it was heavily influenced by the Mirage G and was developed through cooperation between LTV and Dassault for the US Navy's VFX competition. It ultimatly lost to the Grumman 303E/F which later became the F14 tomcat.

The LTV V-507 had access to the AIM54 which would place it in a bad place I fear since im not sure the flight performance or radar are competitive at a min br of 12.7 since it has access to fox 3s.

Pls feel free to add info and correct me on my post, I'd love to have a conversation about the dassault G series

Où peut-on trouver le numéro à trois chiffres sur la proposition parcoursup pour l'inscription ?

Salut ! Je voulais faire mon inscription mais je n'arrive pas à trouver ce fameux numéro à 8 chiffres

Mon n° de dossier ne fait que 6 chiffres, je dois rajouter des 0 avants/après ?

Je suis 289e, le dernier candidat appelé (2025) était le 1740e et le dernier candidat appelé hier était le 1380e. 1380+289=1669 ce qui est inférieur à 1740 donc sa passe non ? Je comprends pas trop comment tout cela fonctionne... Quelqu'un peut-il me dire si je peux me faire accepter svp ?

Question about Gabriel's horn : how do you work out the surface of the acute hyperbolic solid using Guldin's first theorem ?

Hi,

I am a french HS student in 12th grade (which I think is the equivalent of 12th grade in the USA, correct me if im wrong) and I am taking the equivalent of what would be AP Maths and Physics.

For the baccalauréat général (the exams for the end of HS in France), I have to perform an oral presentation about a subject concerning one of the two APs im taking.

My subject is about how we can have solids that can have finite volume but infinite surface area, and Gabriel's horn perfect example of that.

I have no trouble working out the integral to get the volume of the horn, but I dont understand how i can rigorously get the integral of the surface area.

According to Guldin's first theorem, A=α*d*L, where α is the angle of the rotation in radians (in our case, 2π), d the distance from the center of gravity (which should be defined by 1/x but i have no idea if this is rigorous enough) and L the lenght of the arc (which is defined by ∫from 1 to x1 of sqrt(1+((1/x)')²)dx which I have again also no rigorous way to explain to the 2 judges)

On wikipedia, I find that A=2π∫1/x*sqrt(1+((1/x)')²)dx with the integral ranging from 1 to x1, and I'd like to understand how we can get this result

Im asking this because In the oral presentation, there is a 10 minute segment after the presentation where I have to answer the questions of the jury, and I need to be infallible on the matter.

Thanks in advance for the help

NB: sorry for the possible grammar mistakes, english is not my first language
