Показать описание

The derivative of ln(x) is 1/x. We show why it is so in a different video, but you can get some intuition here.

AP Calculus AB on Khan Academy: Bill Scott uses Khan Academy to teach AP Calculus at Phillips Academy in Andover, Massachusetts, and heÕs part of the teaching team that helped develop Khan AcademyÕs AP lessons. Phillips Academy was one of the first schools to teach AP nearly 60 years ago.

Im dumb I thought the anti derivative of lnx was 1/x. But I was going the wrong way

how can you explain the derivative only looking to the graph? I think the explanation is insufficient
