Hi! This is my last question, I need the 2nd and 3rd derivatives of (lnx) / (8x). I have the first derivative as being (8-8lnx) / (64x^2) is that right?? I'm not sure!!! And I need the next 2 derivatives!!! THank you!!!
Let's go back to the first derivative (I didn't see this the first time)
Remember to reduce! You can pull an 8 out of there to get $\displaystyle \frac{1-ln(x)}{8x^{2}}$.
Either way, your answer is technically right.
I want you to simplify it, then post back with that.
After that, you should go ahead and take another derivative.
