    In some ways, this is "backwards" in terms of defining e and hence lnx, but it's still a neat argument, and works if you instead defined lnx to be a certain anti-derivative of 1/x. Nonetheless, you'd still have to show that lnx is itself the inverse of exponential function if you did this, and even then one might wonder why exactly that (1+1/n)^n form is there, though it is apparent when you evaluate the derivatives of log and exponential functions.

    In my younger years, when I was big on math, I worked out this problem in a totally different way, by expanding the expression via the binomial theorem, simplifying each term, and taking the resulting limit of each of those simplified terms. This resulted in the series 1 + 1/1! + 1/2! + 1/3! + 1/4! + 1/5! ... and so on -- Which just happens to come out to 2.71828..., depending on how many terms one adds. In other words, the number e. Go ahead and try it! The procedure in this video is very interesting, but it seems to assume that the value of e is already known. It's nice to be able to plug in all those huge numbers and eventually get the same result, but how would one be able to accomplish that without one of today's calculators? Anyway, I just thought I'd add my two bits!

      They already knew there was a number with special properties in the range of e before they knew with precision what the number was. This technique uses that knowledge to get an e with a higher precision.

    Its a bit circular to use the natural log to derrive e. Is there a proof that doesn't use it?

    MR. Organic Chemistry Tutor, thank you for another outstanding video/lecture on Limits and Logarithms. Although the problem was done correctly, Mr. Organic Chemistry Tutor, you confuse me by mixing up variables/notation. Instead of just letting y equal to (1+1/x )^x and go from there, you have d/dx(ln(1+1/n)/1/n), which is an error. Please correct this error in the video.

    When I was in undergraduate, my teacher proved this theory neither using l'hopital's rule nor the binomial theory. So I know there's a third way proving this theory. I wish I kept my notes because I can't find it on UA-cam. The problem with binomial method is that you have to know the series representation of e. And the problem with the l'hopital's rule is that the function is not continuous.
