# Multivariable Calculus

## Unit aims

To develop an understanding of multivariable calculus including the major theorems of vector calculus.

## Unit description

The course develops multivariable calculus from Calculus 1. The main focus of the course is on developing differential vector calculus, tools for changing coordinate systems and major theorems of integral calculus for functions of more than one variable.

## Relation to other units

This unit feeds into applied mathematics units such as Fluid Dynamics. Applied Partial Differential Equations and Mathematical Methods also use the material.

## Learning objectives

At the end of the course the student should:

- understand the definition of the derivative for multivariable functions.
- be comfortable with vector identities in differential calculus, and differential operators in curvilinear coordinate systems.
- understand and be able to evaluate line, surface and volume integrals.
- understand the main integral theorems of vector calculus.

## Transferable skills

Clear logical thinking, problem solving, assimilation of abstract ideas and application to particular problems.

## Syllabus

- Differentiation of vector functions, operations on maps. Jacobians, inverses, implicit function theorem. Multi-dimensional Taylor's theorem.
- Differential vector calculus: Grad, div, curl. Identities. Summation Convention, Levi-Cevita symbol. Differential operators in curvilinear coordinate systems. Scale factors.
- Integration in vector calculus. Line integrals of vector fields. Surface integrals. Stokes' theorem. Three-dimensional integrals. The divergence theorem, Green's theorem in the plane, Green's identities.
