It is designed to be printed on A3 as a double-sided folded leaflet. Print quality is printer dependant. An onscreen version is available in mathcentre. The leaflets were translated by Dr Tudur Davies, a Coleg Cymraeg Cenedlaethol Lecturer of Mathematics, at the Institute of Mathematics, Physics & Computer Science, Aberystwyth University. Funding from the Coleg Cymraeg Cenedlaethol is gratefully acknowledged.
Communication and Presentation Skills Course PackThis Course Pack offers the resources from a course, titled Communication and Presentation Skills, which sought to teach students how to present numerate information, at an appropriate level, to various kinds of audience. The course sought to develop five key skills in particular: the communication of ideas through speech; the vocal skills needed to speak effectively; the verbal description of quantitative data; the oral interpretation of diagrams and graphs; and, engagement with the audience. The sessions involved active participation by the students, with teamwork an essential element. The materials for the Communication and Presentation Skills course were devised, written and delivered by Eileen Cunningham, Lesley Harper, Shamim Khan, Hendryk Korzeniowski, Gordon Blower and James Groves This resource is free for educational use at UK universities. It is not made available under a Creative Commons licence but is freely available to UK universities for non-commerical educational use.
Composition of functionsWe can build up complicated functions from simple functions by using the
process of composition, where the output of one function becomes the input of
another. It is also sometimes necessary to carry out the reverse process,
decomposing a complicated function into two or more simple functions.
This unit explains how.

Cramer's ruleCramer's rule can be used to solve simultaneous equations using determinants.
This leaflet states and illustrates the rule. (Engineering Maths First Aid Kit 5.2)
DecimalsIn this unit we shall look at the meaning of decimals, and how they are related
to fractions. We shall then look at rounding to given numbers of decimal places
or significant figures. Finally we shall take a brief look at irrational numbers.

Determinants Test 01 (DEWIS)Three questions on finding the determinant of a 2X2 and a 3X3 matrix and finding values of x such that the determinant of a 2X2 is zero.

Diagnosis of Mathematical Skills Among Bioscience EntrantsA paper-based diagnostic test of mathematical skills, presented to Stage 1 undergraduates, revealed that entrants encounter difficulties with some of the basic mathematical concepts that are essential if students are to successfully complete a programme of study within the biosciences. Students reacted favourably towards a number of computer-based learning materials aimed at supporting development of their basic mathematical skills through self-directed learning. However, the availability of such resources made no significant difference to the studentsâ?? overall performance in a subsequent test. Some issues and applications are discussed.
Diagnostic Testing within Institutions - Cardiff UniversityAll students are assessed using a paper-based, but optically marked, written test of 12 multi-choice questions (MCQs). The test covers algebraic simplification, approximation, logs, trigonometry and calculus. It is based on a test developed at Coventry University. It is used to assess students' strengths upon entry.
Diagnostic Testing within Institutions - Keele UniversityAll students are assessed via 20 computer-based multi-choice questions (MCQs). These questions are selected at random from a large question bank, developed jointly by Nottingham and Keele Universities. The main objective is to provide a profile of each studentâ??s mathematical abilities. Each question tests a number of different skills simultaneously and hence contributes to an assessment of the different aspects of this profile. The profile becomes a diagnostic report, which then directs each student to a series of specific modules in â??Mathwiseâ?? that will reinforce their knowledge and correct any problems.
Diagnostic Testing within Institutions - UMISTAll students are assessed using a paper-based written test on their first day in the department. The students are allowed to use any non-graphical calculator to help answer 48 questions of the type and standard that they should be familiar with from A-Level. The questions range across simple arithmetic and algebra through logs to differentiation and integration, finishing with some questions on vectors. Final solutions are filled in on an answer grid. The temporary streaming of the students is based on the results.
Diagnostic Testing within Institutions - University of BristolAll students are tested via two computer-based tests each consisting of 10 multi-choice questions (MCQs). These tests are set from a large bank of questions using the â??TALâ?? (Teach And Learn) computer system developed at the University of Bristol. The topics covered include arithmetic, algebra, geometry, functions, calculus, and probability. A â??leave unansweredâ?? option is provided and negative marking used to discourage guessing. The tests are accessed through a Web interface, so in principle could be accessed from anywhere. It has been run with large-scale simultaneous access and, although a little slow, is relatively robust.
Differential Equations Test 01 (DEWIS)Four questions on second order linear constant coefficient differential equations. The first two involve identifying the complementary function, the third involves applying initial conditions and the fourth involves finding a particular solution with either linear or sinusoidal forcing.
