## Mathematical Methods (MAGIC022) |

## GeneralThis course is part of the MAGIC core. Description
This is a core applied module. The aim of the course is to pool together a number of advanced mathematical methods which students doing research (in applied mathematics) should know about. Students will be expected to do extensive reading from selected texts, as well as try out example problems to reinforce the material covered in lectures. A number of topics are suggested below and depending on time available, most will be covered. The course proceeds at a fairly fast pace.
Assessment
The assessment for this module will be in the form of a take-home exam at the end of the course.

## Bibliography
Note:
Clicking on the link for a book will take you to the relevant Google Book Search page. You may be able to preview the book there. On the right hand side you will see links to places where you can buy the book. There is also link marked 'Find this book in a library'. This sometimes works well, but not always. (You will need to enter your location, but it will be saved after you do that for the first time.) ## AssessmentAssessment for this course will be via a take-home examination which will be put online towards the end of the course (8th December) and for which the deadline for completion will be 15th January. The exam paper will require the completion of 4 out of 6 questions and to pass one is required to obtain at least 50%.
