### Purpose

The component provides an essential grounding in mathematical methods for all students enrolled in the Intercalated B.Sc. in Medical Physics & Bioengineering. A significant proportion of the course covers material that in previous years was covered in group tutorials, which proved to be a very important element of the intercalated programme. The component will provide students with sufficient knowledge in mathematics in order that they are at no significant disadvantage compared to 3rd and 4th year physics and electrical engineering students who also take the other courses which form the intercalated degree.

### Aims and Objectives

The aim is to provide intercalating medical students with the most fundamental skills in mathematics and statistics which are essential for a thorough understanding of the most important physical principles and techniques in medical physics. The specific objectives are to introduce students to a series of mathematical topics necessary for their comprehension of other components of the intercalated programme, and to engender a proficiency in statistics and basic analytical techniques.

### Teaching and exams

Teaching will consist of:

- Lectures, 30 hours.
- Seminars/problem classes, 6 hours.
- Required written work 4 coursework sheets (problem sheets).
- Private reading 45 hours.

The assessment will consist of:

- 1 Unseen written examination (2.5 hours) worth 80% of the total course mark.
- 3 Problem Sheets completed during term-time worth 20% of the total course mark.

### Prerequisites

This module is for Intercalating Medical Physics students only. An A Level in Mathematics (or its equivalent) is required, although some exceptions are sometime made where students are prepared to undertake additional directed learning during the summer prior to starting the course.

**Specific knowledge
assumed:**

**Mathematics**: Familiarity with
manipulation of equations, basic calculus (differentiation and integration),
exponentials. Ability to sketch graphs.

**Physics: **None.

**Engineering:** None

**Biology: **None.

**Other: **None.

### Description

The course, taught during Term 1, is designed specifically for intercalated students in order that they gain a basic familiarity with various mathematical techniques and notation which form part of their other lecture courses. It is intended to be sensitive to the current mathematical skills and limited previous experience of medical students, including the minority without A'level Mathematics (although such students are expected to undertake some directed background reading during the summer before starting the intercalated degree). The lectures emphasise the need for an intuitive understanding of specific methods and their application rather than a rigorous training in mathematics. The course will also enable students to develop greater skills to process and manipulate data, which forms a significant part of most student projects.
