The following question is similar to June 2008 GCE O Level A-Math Paper question which is testing on the following concepts
Differentiation involving exponential (I have written a post on Differentiation of e; post on Basic Differentiation Techniques are available here too )
Finding coordinates and nature of stationary point (Application of Differentiation)
Watch the video for a few more important tips on handling this sort of question.
Hi, I'm Ai Ling. I enjoy coaching students who have challenges with understanding and scoring in 'O' Level A-Maths and E-Maths.
I develop Maths strategies, sometimes 'ridiculous' ideas to help students in understanding abstract concepts the fast and memorable way.
I write this blog to share with you the Maths tips and strategies I teach in my class. I hope all these will help you to enjoy Maths and achieve better results.
[...] Stationary points (Includes a video on the step by step solution) [...]
There is a small error in your video clip on “A-Math: Find Coordinates and Nature of Stationery Point (Plus: Tips to note in Differentiation)” if I m not wrong.
-2x 4x 4x -2x
-4e (e – 3) + 4e (2e )
-2x 4x 4x
= 4e ( -e + 3 + 2e )
-2x 4x
= 4e ( e + 3)
