Very often, differentiation of ln involves simplification first. By using ln rules, I was able to simplify the given question before I start differentiating.
So all students should know the ln rules well, which are very similar to logarithms rules.
I hope this step-by-step approach allows you to understand better on how to differentiate ln.
This is my first video using flipvideo.
I know the ‘whiteboard’ section is slightly shaky and blur; I’ll improve in my next video.
I would love to hear from you! Leave me a comment!

Qn frm email (Additional Mathematics Question / A-Math Questions)
Differentiate ln square root (2x+4)
Hint#1: Bring out Laws of Ln which is somewhat the same as Laws Of Log :)
Hint#2: When you are asked to Diff Ln (whatever) = Diff (whatever) OVER (whatever) :)

Amaths Differentiation and Integration techniques.
How to actually remember all the different ways for differentiating and Integrating, I always get mixed up
Hi xxx,
Differentiation = Decrease Power
Integration = Increase Power
(It’s often sth OVER another)
Example
Diff e^2x = 2e^2x
Integrate e^2x = (e^2x / 2)
Diff (3x+4)^5 = 5(3x+4)^4 (3)
Integrate (3x+4)^5 = (3x+4)^6/(3*6)
It’s suggested that you have a “cheat” sheet with Diff on Left Hand Side and Integration on Right Hand Side.
To familiarise more, work on at least 5 qns just on differentiation and integration :)
You can always scan me any qns or type out any should you face any challenges.
Cheers,
