Preparatory Reading and Lecture Notes: Term 1

The term 1 course is very well covered in the book by Stroud. It will assume that you know the Foundation Topics in Part I. Chapters F11 and F12 on Differentiation and Integration are especially important.

Almost all the course is at the level of Part II of Stroud s book, and covers the following Chapters: 1 and 2 (Complex numbers), 3 (Hyperbolic functions), 6 (Vectors), 7 and 9 (Differentiation), 13 and 14 (Series), 15 and 17 (Integration), 24 and 25 (Differential equations).

The book by James also covers the course well, and comes with the online course MyMathLab if you buy it new. Pearson offers a discount on this book if you also buy Young and Freedman s University Physics.

The book by Boas is more advanced - it is a recommended text for Year 2 Mathematics, and has some sections that are used in Year 1.
