The course is therefore very essential for all students who need a very good founda- tion in mathematics to undergo any degree programme in the sciences. The course treats a very broad combination of all the major mathematics topics contained in the syllabuses of the West African Examination Council (WAEC), National Examinations Council (NECO) and Joint Admissions and Matriculation Board (JAMB). By the time you have successfully gone through this course, you would have mastered so many methods of solving various fundamental problems in mathematics that are essential to your subsequent studies in higher mathematics or any science programme that employs much of math- ematics. You are expected to diligently go through the course materials, do the exercises contained in the course and do the tutor-marked assignments (TMAs) at the end of each unit. Before you end this course, you would have become more grounded in your understanding of general basic math- ematics essential for your intended undergraduate programme. However, to profitably go through this course and communicate with your course tutor over the internet, you will need to have access to a computer system that has the minimum configuration listed under the course materi- als. What you will learn in this course This course is aimed at taking you through all the various topics in mathematics at a pre-degree level in order to lay a good foundation for a sound mathematics baaground which is a pre- requisite for all science and science-related courses of NOUN's undergraduate programmes. Mathematics MTH 001 C Aims of the course The above overall aim are to: i) Solve problems involving bases, indices and logarithms. ii) Identify and solve various types of equations such as linear, simultaneous and quadratic equations and those involving surds. iii) Solve various problems of mathematics covering areas in sets, trigonometry, differentia- tion, integration, measuration, plane and coordinate geometry and simple statistics. iv) Lay a good foundation in the basic concepts and applications of mathematics principles. Course objectives On successful completion of the course, you should be able to: i) Solve problems in different number bases. ii) Explain the relationship between indices and logarithms. iii) Identify surds and solve equations involving surds. iv) Distinguish between arithmetic progression and geometric progression. v) State the properties of sets and represent them using Venn diagrams. vi) Solve linear and simultaneous equations, and to also solve the latter by graphical method. vii) Identify quadratic equations, solve them using various methods and plot their graphs. viii) Solve inequalities and represent them graphically. ix) Explain various types of variation and how to convert them into equations. x) Solve problems involving matrices and calculate determinants of matrices. xi) Employ various properties of plane geometry involving polygons, angles and circles to solve related problems. xii) Calculate volumes of solid shapes. xiii) Define trigonometric ratios and apply them in solving problems of triangles and bearings. xiv) Coordinate geometry. xv) Discuss various ways of representations of statistical data and solve simple probability problems. xvi) Define differentiation and integration of a function and apply the definitions in so!‘ ing related problems. xvii) Solve simple problems of permutations and combinations. Working through this course Course materials You will need some materials to have a successful study trip through this course. The materials are mainly the reference textbooks listed below under set textbooks.

Tutor-marked assignments- . There are tutor-marked assignments (TMAs) at the end of each unit. You are expected to do the assignments and submit them to your tutor for assessment. Mathematics MTH 001 C vii Final examination and grading The successful completion of this course depends on passing an examination at the end of the course and the satisfaction of all the conditions given by the National Open University of Nigeria. Course marking scheme You can have access to the solutions of all your assessment questions from your tutor for the course. How to get the most from this course To get the most from this course, you need to keep diligently to the study guidelines given by the National Open University of Nigeria. Such guidelines include the study hours expected to put into your study and doing all your assessments. Summary This course is an indispensable course you need as a trainee preparing for a degree programme in any of the sciences or science-related programmes. For example, you cannot be sufficiently prepared to pursue a successful programme in computer science if you do not have a good background in mathematics because computer programming utilises a great deal of mathematical principles and expressions. It takes discipline and constant practice to master almost any mathematics topic. Hence you need to study closely all the examples and also do all the exercises in this course. A list of a number of references is included in this course to give you opportunity to explore the rich resources you need to build yourself up as a good student of basic mathematics. Tutors and tutorials You need to interact with your tutors and attempt all tutorial classes for a better understanding of this course. viii Mathematics .

For example, our most familiar number system, that is, the decimal system is based on number 10 and it has 10 symbols or digits. It has generally been assumed that the use of the decimal system was developed from the fact that human hands have 10 fingers which are readily available for calculations.

  • Mathematics at the Grange
    MATHEMATICS AT THE GRANGE At the Grange we offer three sixth form mathematics options: Mathematics – single option choice leading to A level Mathematics Further Mathematics – double option choice leading to A level Mathematics and A level Further Mathematics AS Mathematics – 4th option choice leading to AS Mathematics. Before deciding which the right choice is for you, make sure you read all three sections in this booklet. MATHEMATICS Whilst the A Level Mathematics course builds on the knowledge gained when studying GCSE, the emphasis is Course different. Algebra still has a central place, as this is the language in which the subject is expressed, but more importance than Content before is attached to being able to produce clearly reasoned arguments. You will build up a toolkit of mathematical methods, and you will learn how to become an effective problem-solver. You will make much greater use of technology to explore concepts, to exploit links between graphs and the underlying algebra, and to process data. There will be a greater focus on doing mathematics in the context of real-world problems. In common with all A Level syllabuses, two thirds of the Edexcel specification is pure mathematics and the remainder applied. Pure mathematics is the study of mathematical methods for their own sake, and you will gain a grounding in topics such as algebra, calculus (the study of gradients and areas under curves), numerical methods, trigonometry, vector geometry and differential equations. In applied mathematics, you put the techniques you have learnt to use in modelling real life situations: in mechanics you study forces and motion, and in statistics how to use mathematical rules to simplify complex probability calculations and how to analyse sets of data and draw reliable conclusions.
