(lne) 'why = 1 / X Can you prove it


The title is (LNX) '= 1 / X
The proof process is a little complicated. You can see the chapter of differential calculus in the fifth edition of higher mathematics published by Tongji University. I can't type it out



What is the result of lne in mathematics?

How much math is lne2 equal to


It should be ln (e ^ 2) = 2lne = 2
If ln (2e) = LN2 + lne = LN2 + 1
