You actually 𝑐𝑎𝑛 integrate 1/x using the power rule (with a little help from l'Hôpital)pic.twitter.com/tvuQrjFFmC

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...

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
