First off, the natural logarithm is abbreviated (an L not an I).
Recall the definition of a derivative of a function at some point x = a:
So imagine: and a = 1.
Perhaps someone could explain the last step here for me please...
Find the limit of . Do not use L'Hopital's rule.
Since In(1) = 0, we have that,
= = for x =1. (Not quite sure how to do the latex for the way its written in my notes. To the right of the d/dx is a vertical line with x=1 at the bottom.)
And... Im not quite sure how to do the last step there i.e the = bit...
Any help on this?
