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.
Many students don’t like the topic in A-Math known as ‘Kinematics’. My guess is that it is linked closely to Physics which is a subject not favourited by many too.
To be able to understand Kinematics, I always get my students to be familiar with what I call a ‘Kinematics Vocabulary List’. [Click here to download a printable note]
I hope you find this list useful. I would like to hear from you how you find Kinematics in Differentiation & Integration. Do you like it or dislike it? Leave me a comment.
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!

One of the applications of Differentiation is to determine the type of stationary point. This application is common in maximum and minimum problems.
There are two ways to go about finding the type of stationary point. The more frequently used method is through Second Derivative (Watch the video here). (d^2y/dx^2)
However, I’m not going to discuss on that method. Instead I want to share with you on the less popular method which is First Derivative. The reason: I have observed that last 2 years, questions appearing in the GCE ‘O’ level Additional Mathematics were less commonly seen, least expected and definitely more nerve breaking for candidates who aren’t prepared.
Let’s take a look at how First Derivative is applied.

understanding and scoring in 'O' Level A-Maths and E-Maths.
