It's a simple process once you know the basics behind it.Let's take X²We have been asked to integrate this.The first thing is to always add 1 on to the power.X³Next thing is to divid...

The key point in this question is noting that implicit differentiation is a very useful tool, although it is slightly different and looks much scarier than differentiating y = f(x).To do the question, a m...

Stationary points are points on a curve where the gradient is zero. There are three types of stationary point maximum, minimum and point of inflexion. (will draw diagrams). They can be found by differenti...
