You ought to have this memorized.
for y= ln x
dy/dx = 1/x
This is the most basic and fundamental of log derivatives.
If you are studying Calculus, and the topic is logs, I fail to understand why you asked that question.
IS there a website that can better explain logs?
Hmmm. This is an odder question, for a person taking calculus. I suspect you need to ask yourself the question if you are in over your head.
I can recommend Schaum's Outline Series: College Calculus, a very good problem oriented book. It is about 17 dollars at your college bookstore, or BarnesNoble, or Amazon. It is well worth it.
Now your question "better explain logs".The problem did not deal with logs, it dealt with a basic differential of a log function. That should be memorized, just as d(sinx)/dx is memorized as cosx.
If you want help in log functions. try
This a basic tutorial for precal students.
Thanks for the info..And yes I may be in over my head, but with my grades you wouldnt know it...So far so good...
