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. [Read more...] about A-Math: Type of Stationary Point through First Derivative
