Dude what you're calling de l'Hôpital rule is just the definition of a derivative...

Il utilise bien la règle de l'Hôpital pour la limite du terme de droite.

J'ai du mal à le voir... Et y'a tellement de choses qui me gênent dans sa vidéo, comme avoir x dans les bornes et l'intégrande de son intégrale...

'so many' [says one thing]

You want a list? 1/ Having x both in the bounds and the integrand; 2/ the initial limit/integral exchange; 3/ the denominator being linear, you differentiate rather than use de l'Hôpital ; 4/ n is an integer, I don't like making it real to take the limit; 1/2

1. fair point, but like it or not it's completely clear 2. see thread 3. l'Hôpital says you differentiate both numerator and denominator 4. the power rule is not just true for integers

1. No it's not, I would remove points on an essay if a students wrote it 2. Yes I know why it is valid, but then put in the video 3. True but as we say in French it's like using a drill to kill a fly 4. True but it's not very pedagogical (pretty sure my undergrads would cry)

1. I will accept this as valid 2. No, just read a little more 3. "true" is all i needed 4. "true" is all i needed
