Is There A Name for the Function <math>f(x)=x^{1/x}</math>?

I was aware of the existence of this article in Wikipedia, but forgot its title, so I was unable to find it until I found the title from an earlier note. I suppose people look for "x raised to 1 over x" or "the xth root of x". --Roland (talk) 05:29, 11 September 2017 (UTC)

are you sure?

To find an extreme of a function, you look for zeros, not maxima, of its first derivative. Or at least that's how I have always done it. —Tamfang (talk) 01:11, 3 May 2025 (UTC)

:the maxima of the first derivative corresponds to where the second derivative is 0 and the third derivative is negative. But if I'm reading the article correctly - that's not what is being done! the natural logarithm is first taken, and *then* the derivative, then some logic about the slope around x=e. --Bumpf said this! ^{ooh clicky clicky!} [insert witty meta-text on wiki-sigs here] 03:20, 8 May 2025 (UTC)
