**General description**

This module covers the algebra and calculus which are fundamental to the development of mathematics.

**Aims**

To introduce students to the ideas of algebra through the study of complex numbers and polynomials; to establish a clear understanding of the ideas of limit and derivative; to develop technical facility in calculations involving limits and derivatives and to develop techniques for determining definite and indefinite integrals.

**Learning outcomes**

On completion of this module, a student should be able to:

- use the notation for sets and mappings;
- construct proofs using the Principle of Mathematical Induction;
- apply the Binomial Theorem for an integer exponent in various situations;
- obtain the sums of arithmetic and geometric series;
- manipulate complex numbers and use DeMoivre's Theorem;
- use the Division Algorithm for polynomials;
- derive identities involving the roots of a polynomial and its coefficients;
- sketch the graphs of simple functions;
- calculate the limits of real valued functions;
- determine whether given functions are continuous or not;
- explain the idea of derivative and compute derivatives from first principles;
- explain the notion of inverse function;
- derive the formulae for the derivative of products and quotients of functions;
- compute the derivative of functions;
- determine the local maxima and minima of functions and their points of inflexion;
- compute integrals by the methods of substitution and integration by parts;
- compute integrals of rational functions and trigonometric functions.
