3.2.4 MATHEMATICS FOR ENGINEERS AND SCIENTISTS –MATH1551 (62 lectures)

Dr D. J. Smith/Dr C. Kearton

This module is intended to supply the basic mathematical needs for students in Engineering andother sciences.

The first lecture will be replaced by a short diagnostic test. This test is based on a wide range ofmaths A-level material. The purpose is to help you brush-up on any material you have forgotten ordid not cover in great detail at A-level (not everyone has the same mathematical background.) Itdoes not count in any way towards your final mark for this module. Note that there are also revisionclasses during the first two weeks of term where you can practise problems and ask questions.

There are 3 lectures each week and fortnightly tutorials. The tutorials starts in Week 3. Problemswill be set to be handed in each week and there is a Collection examination in December. All theseform an integral part of the module.

Recommended Books

Students should buy either the two books by Stroud or the book by Stephenson.

K.A. Stroud with additions by Dexter J. Booth,Engineering Mathematics, Palgrave Macmillan(5th edition paperback), ISBN 0333919394K.A.Stroud with additions by Dexter J. Booth,Advanced Engineering Mathematics, PalgraveMacmillan (4th edition paperback), ISBN 1403903123G.Stephenson,Mathematical Methods for Science Students, Longman.

If you are not too confident about the mathematics module then the books by Stroud will provideyou with much support throughout the module. Students found these books very helpful in previousyears. You will probably already know some of the material in the first book. Stephenson is amore concise text but should prove useful for parts of the second year mathematics module forEngineering students.
