I'm really having some difficulty understanding how to find the derivative of log functions - I keep trying these homework questions and getting most of them wrong and I'm really starting to get annoyed.
Here's a question, for example:
I did attempt it several times, different ways but each time it was wrong...
Any hints on how to go about these sorts of questions? I know that you're supposed to use the chain rule but it's just not working for me for some reason.
Any help's appreciated!
