The star players in this module are the trigonometric and exponential functions, and their inverses. These are the first functions we meet that go beyond polynomial and rational functions, which are generated by simple arithmetical operations. We first meet trigonometric functions in right-angled triangles, and exponential functions in considering how few powers of 10 separate atoms from galaxies. In this module we shall see how these two types of functions, coming from such different sources, are intimately linked (but only when we allow complex numbers, involving the square root of minus one). We shall be especially concerned with their special role in calculus, exemplified by their appearance together in the solutions of differential equations in the last part of the module. In preparation, we shall seek a thorough understanding of differentiation and integration, and we begin with some foundational material on sets, functions and counting, on which much of mathematics can be built.
There are no prerequisites for this module.
