# MA259-10 Multivariable Calculus

##### Introductory description

Mathematical Analysis is the heart of modern Mathematics. This module is the final in a series of modules where the subject of Analysis is rigorously developed in many dimensional setting.

##### Module aims

extend the analysis of one variable from the first year to the multivariable context.

##### Outline syllabus

This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.

- Different notions of continuity of functions of several variables
- Quantitative Linear Algebra in terms of norms
- Different notions of differentiability of functions of several variables
- Chain rule, (generalised) mean value inequality and other properties of differentiable functions
- Inverse Function Theorem and Implicit Function Theorem, with applications to regular curves and hypersurfaces
- Vector Fields and the theorems of Green, Gauss and Stokes, with some applications to PDEs.
- Maxima, minima and saddles and constrained critical points.

##### Learning outcomes

By the end of the module, students should be able to:

- learn the basic concepts, theorems and calculations of multivariable analysis
- understand the Implicit and Inverse Function Theorems and their applications
- acquire a working knowledge of vector fields and the Integral Theorems of Vector Calculus
- learn how to analyse and classify critical points using Taylor expansions

##### Subject specific skills

Multivariable Analysis gives students tools to do rigorous Analysis in higher dimensional spaces. Students will learn definitions, theorems and calculations with vector-valued functions of many variables, for instance, Inverse and Implicit Function Theorems, vector fields, maxima, minima and saddles.

##### Transferable skills

Students will acquire key reasoning and problem solving skills, empower them to address new problems with confidence.
