Differentiation is the maths of changeable variables. In science, what is truly important is not what value something has at the moment; however what value it will have. This is where the differentiation comes in. By differentiating a variable, we obtain the rate at which it is changing. To start with, we consider the gradients of curves; however soon move on, to apply differentiation to quantities changing with time.
