Earlier algebraical methods are usually indequate to solve the resulting mathematical problems, so that methods of differential calculus, introduced by the first example, are needed.

,Calculus (ii)—Integration and Differential Equations, changed in relationship to a variable, where the rate itself was in continuous change. Each calculation involved an analytical or ‘narrowing down’ process, conveniently summarised in the relationship.e.g. in Example 7.1, we have.This chapter considers the inverse relationship.
