I thought I knew how to do this but I keep coming up with the wrong answer. Here is what I've done:
Then multiply with the original y to get:
But the answer I'm seeing has in there instead of the original y value.
Any help would be appreciated.
I would suggest that instead of taking the log, you change the function to the following form:
, which is equivalent because .
Then, use the chain rule to find the derivative:
Edit: actually, your answer is correct. Perhaps the reason for the discrepancy is that they distributed and changed
These are equivalent because .
