Timing and Structure
Michaelmas Term: 3 lectures per week, weeks 1-8; Lent Term: 2 lectures per week, weeks 5-8; Easter Vacation: Programmed Learning Exercise: Easter Term 2 lectures weeks 1-3, 1 in week 4: 39 Lectures
The aims of the course are to:
- Instill fluency with the basic mathematical techniques which are needed as tools for engineers.
- Revise, and teach afresh where necessary, those parts of the A-level mathematics syllabuses which are necessary for the first two years of the engineering course, and to introduce those new mathematical techniques which are necessary for these courses.
- Place emphasis throughout upon the grasp of essentials and competency in manipulation.
As specific objectives, by the end of the course students should be able to:
- Recognise the appropriate mathematical tools and techniques (from the following syllabus) with which to approach a wide variety of engineering problems.
- Specify a mathematical model of a problem.
- Carry out appropriate mathematical manipulations to solve the modelled problem.
- Interpret the significance of the mathematical result.
Michaelmas term (streaming 24L with access to recorded material for fast revision)
The Michaelmas term course concerns revision and extension of concepts which most students will have met at school. In previous years this course has been presented in two versions: a "24 lecture standard pace" and a "16 lecture fast pace." For the online presentation format only the 24 lecture standard pace (three lectures per week) course will be presented. The lectures notes will be made available beforehand and the lectures will be streamed according to the timetable. After each lecture the recorded material will be made available and indexed to the lecture notes. Students who have taken double mathematics at A level and who have good mathematical fluency (and would have attended the fast pace lecture course in previous years) may choose to just read the lecture notes and, where necessary, refer to the appropriate recorded material. Examples papers will include exercises to encourage students to practice mathematical skills learnt in their previous studies.
