Differentiation involves examining the behaviour of gradients to a curve at a given point.
In other words, the infinite series e x remains the same after differentiation. Identifying the type of function However before we begin to differentiate your initial strategy will be to identify the type of function. Categorising the function helps you determine the appropriate method to apply when finding the derivative. The chain rule differentiate the function of function. When you are clear about the different categories, make your own notes in your book then move to the first activity.
