### Course Aims

This course extends the basic concepts of differentiation and integration learned in Mathematics 1 to the operations on functions of multiple variables. Advanced applications of differential and integral calculus are included. In addition, the course covers topics on sequences, series and ordinary differential equations.

This course aims to equip you with
• mathematical knowledge and analytical skills so that you are able to apply techniques of advanced calculus (along with their existing mathematical skills) to solve engineering or scientific problems whenever applicable;
• mathematical reading skills so that you can read and understand related mathematical content in the basic and popular scientific and engineering literature; and
• mathematical communication skills so that you can effectively and rigorously present your mathematical ideas to mathematicians, scientists and engineers.

### Intended Learning Outcomes

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

1. Express the general term of a sequence, determine and evaluate the limit of a convergent sequence, apply squeeze theorem for sequences, explain why a sequence is convergent or divergent.
2. Manipulate basic series such as geometric series, telescoping series and determine its convergence and sum. Identify properties of convergent and divergent series.
3. Determine whether a series is divergent by Divergence Test. Apply alternating test to determine an alternating series is convergent. Apply integral test, comparison test and limit comparison test, ratio test, and root test appropriately to series to determine convergence of series with positive terms. Determine absolute, conditional or divergence of a general series,
4. Manipulate some power series related to geometric series; determine the radius and the interval of convergence for power series. Apply term-by-term differentiation and integration of power series. Apply power series to approximation.
5. Evaluate Taylor’s series (Maclaurin series) of functions, including exponential and sine functions. Determine Taylor series of some functions using known Taylor series. Use the Taylor’s Remainder Theorem and Estimation theorem to determine the upper bound of the estimation error of a series.
6. Determine the domain of simple 2-variable function and sketch the domain and level curve.
7. Evaluate the limits of 2-variable and 3-variable functions; explain why the limit does not exist.
8. Interpret the concept and meaning of partial derivative and evaluate partial derivatives. Apply Chain rule for partial differentiation.
9. Evaluate the gradient vector and use its orthogonality to determine the equation of tangent plane to a level surface and the graph z=f(x,y). Determine the equation of normal line. Apply the equation of tangent plane to z=f(x,y) to linear approximation. Use total differential to approximate the errors or changes.
10. Evaluate directional derivative, and use it to determine rate of change.
11. Find stationary points and classify them as local maximum, minimum or saddle points.
12. Use Lagrange Multiplier method to determine global maximum or minimum of a function subject to an equality constraint. Apply the method to solve optimization problems.
13. Sketch the region of integration for 2-variable function and evaluate double integral, and apply it to some problems. Generalize the concept of double integral to triple integrals.
14. Solve separable first order ordinary differential equations (ODEs), homogeneous first order ODEs, first order linear ODEs by integrating factors, Bernoulli's equations and exact ODEs.

### Formative Feedback

Instructors and tutors will discuss tutorial solution and common mistakes in student work during tutorial sessions or lectures or via online materials.

### Learning and Teaching Approach

 Lectures (26 hours) Derivation of formulas and demonstrating problem solving: Train you to be independent learners who are able to derive ideas/concepts from first principles and take ownership of your own learning. Help you understand the motivation behind mathematical theorems, definitions and formulas. Develop the train of thought in problem solving and presentation skills in presenting mathematical solutions. Problem solving: Develop competence in solving related problems. Peer Instruction: Develop communication skills and competence in mathematics. You also have an opportunity to work with your peers during lectures and tutorial sessions. Tutorials (12 hours) Derivation of formulas and demonstrating problem solving: Train you to be independent learners who are able to derive ideas/concepts from first principles and take ownership of your own learning.

### Course Policies and Student Responsibilities

Absence Due to Medical or Other Reasons
If you are unable to attend a common test with a valid reason, you have to:
1. Send an email to the instructor regarding the absence.
2. Submit the original Medical Certificate* or documents (if it is not due to medical reason) to administrator (in School Office).

* 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.
