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.
