I'd like some help on derive a function and simplifying the expression as much as possible.
Here's my idea on how it ends up...
first, we can work a little bit with the function:
Ok this looks a bit easier, we'll get the derivate of an product.
The general derivate of ln:
and simply ends up as
Let's move on...
I think it looks correct, can it be simplified?
Thanks for all replies.
