Differentiating exponentials and logarithms
Hey guys, how do you differentiate ln(3x-4) and and ln(2-x/3-x)?
Thank you!!
Thank you!!
Use this: http://examsolutions.net/maths-revision/core-maths/differentiation/methods/chain-rule/lnf(x)/tutorial-1.php and http://examsolutions.net/maths-revision/core-maths/differentiation/methods/quotient-rule/tutorial-1.php
It's easier to learn the method than to ask every time you have doubts! But if you're still not sure, I'll try to help.

Do you know how to differentiate ln(x)?
Have you earn the chain rule?

The second one will be easier to differentiate if you use log rules to split it up, aside from this these are two fairly simple differentiation problems.
Have you learnt the f'(x)/f(x) rule for differentiating natural logs?
