A-Math: Find Coordinates and Nature of Stationery Point (Plus: Tips to note in Differentiation)


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 )

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 Math 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 stuff I teach in my class, the common mistakes my students made, the 'way' to think, analyze... If you have found this blog post useful, please share it with your friends. I will really appreciate it! :)

    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)
