Type of module:

Summary module description:

In this module the concepts of analysis are generalized to a multidimensional context. It is 16 weeks long.

The Module lead at NUIST is Dr Wu Xiaoxing.


To revisit familiar notions of analysis, in particular limits and continuity, in terms of analytical and geometrical concepts, and extend them to a more general setting. To define differentiation and other topics including integration in a higher-dimensional setting.

Assessable learning outcomes:

By the end of the module students are expected to be able to:

  • understand the topological basics of analysis and the geometrical nature of the concept of convergence;

  • define the notions of continuity and differentiation in a rigorous way for functions of several real variables;

  • describe critically the difference between total and partial derivative and the practical consequences;

  • apply derivatives to estimate loca l behaviour rigorously.

  • master the calculations of multiple integrals, line integrals and surface integrals, and the connection between them via the integral theorems of Green, Gauss and Stokes.

Additional outcomes:

Students should reflect on the concept of locality and local standard representation of differentiable functions.

Outline content:

Week 1 Limit and continuity for functions of several variables              

Week 2 Partial derivatives of a function, geometric interpretation, chain rule,directional derivatives and gradients (points of importance and difficulty: higher-order partial derivatives)

Week 3 The mean value theorem and Taylor 's theorem for several variables, extreme value (points of difficulty: calculate extreme values)

Week 4  Implicit functions, curves and surfaces in implicit form, geometric applications (e.g. tangent plane and normal line of a surface), conditional extreme values     

Week 5 Parametric integrals(proper and improper)

Week 6& nbsp; Parametric integrals(points of importance and difficulty: uniform convergency, Euler integration)

Week 7  Multiple integrals(double integrals, concept and property, Fubini’s theorem)

Week 8  Reduction of double integrals to repeated single integrals, (points of importance and difficulty: transformation of double integrals, Polar coordinate transformation)

Week 9  Triple integrals, applications of multiple integrals (area of a surface, mass center)

Penalties for late submission:

The Support Centres will apply the following penalties for work submitted late:

  • where the piece of work is submitted after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for that piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
  • where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.
The University policy statement on penalties for late submission can be found at:
You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.

Assessment requirements for a pass:

A mark of 40% overall.

Reassessment arrangements:

One examination paper of 2 hours duration in August/September - the resit module mark will be the higher of the exam mark (100% exam) and the exam mark plus previous class test and coursework marks (70% exam, 30% coursework).
