#### Course Aims

This course introduces the mathematics crucial to mechanics, dynamics, electromagnetism, fluid flow, financial modelling and many areas of pure and applied mathematics. The course combines and extends the ideas from one variable calculus and linear algebra to develop the calculus of functions in R2 and R3. The final topic is an introduction to Fourier series, which concerns the representation of functions of a single real variable by infinite trigonometric series. In this course, the connection between diagrams/visualization and symbols is particularly important. Understanding that relationship is one of the main aims of the course.
