Calculus III is a core Mathematics course that extends concepts and techniques developed in Calculus I and Calculus II to the case of functions of several real variables. In other words, we try to do the same things as in Calculus I and II, but in higher dimensions. In this course, we shall discuss the notions of limits, continuity, derivatives and integrals of real-valued and vector-valued functions of many variables. Most of the time, extending these familiar notions from one to several variables requires some degree of ingenuity, and we are going to have to spice up the material from Calculus I and II with a little bit of geometry and linear algebra.Techniques learned in Calculus III are essential for financial analysts, engineers, and for further study in mathematics.

Upon successfully completing this course, you should be able to:

- Parametrise curves and their tangents;
- Approximate and optimise multivariate functions;
- Apply the chain rule to multivariate functions;
- Find volumes of geometrical objects in higher dimensions;
- Parametrise surfaces and their tangent planes;
- Recognise when it is appropriate to use cylindrical and spherical coordinates;
- Determine the div and curl of a vector field and recognise the physical interpretations of these quantities;
- Apply Stokes’ theorem and its specialisations to simplify relevant problems;
- Apply multivariate calculus to real-world problems.

Absence due to medical or other reasons

If you are sick and unable to attend a midterm you must:

1. Send an email to the instructor regarding the absence.

2. Submit the original Medical Certificate* to an administrator.

*The Medical Certificate mentioned above should be issued in Singapore by a medical practitioner registered with the Singapore Medical Association.

Good academic work depends on honesty and ethical behaviour. The quality of your work as a student relies on adhering to the principles of academic integrity and to the NTU Honour Code, a set of values shared by the whole university community. Truth, Trust and Justice are at the core of NTU’s shared values.

As a student, it is important that you recognize your responsibilities in understanding and applying the principles of academic integrity in all the work you do at NTU. Not knowing what is involved in maintaining academic integrity does not excuse academic dishonesty. You need to actively equip yourself with strategies to avoid all forms of academic dishonesty, including plagiarism, academic fraud, collusion and cheating. If you are uncertain of the definitions of any of these terms, you should go to the Academic Integrity website for more information. Consult your instructor(s) if you need any clarification about the requirements of academic integrity in the course.
