Intended Learning Outcomes (ILOs)

What is the main purpose of this course?

The goal of the course is to study basic mathematical concepts that will be required in further studies. The course is based on Mathematical Analysis I, and the concepts studied there are widely used in this course. The course covers differentiation and integration of functions of several variables. Some more advanced concepts, as uniform convergence of series and integrals, are also considered, since they are important for understanding applicability of many theorems of mathematical analysis. In the end of the course some useful applications are covered, such as gamma-function, beta-function, and Fourier transform.

ILOs defined at three levels

We specify the intended learning outcomes at three levels: conceptual knowledge, practical skills, and comprehensive skills.

Level 1: What concepts should a student know/remember/explain?

By the end of the course, the students should be able to ...

  • know how to find minima and maxima of a function subject to a constraint
  • know how to represent double integrals as iterated integrals and vice versa
  • know what the length of a curve and the area of a surface is

Level 2: What basic practical skills should a student be able to perform?

By the end of the course, the students should be able to ...

  • find partial and directional derivatives of functions of several variables;
  • find maxima and minima for a function of several variables
  • use Fubini theorem for calculating multiple integrals
  • calculate line and path integrals

Level 3: What complex comprehensive skills should a student be able to apply in real-life scenarios?

By the end of the course, the students should be able to ...

  • find multiple, path, surface integrals
  • find the range of a function in a given domain
  • decompose a function into infinite series

Recommendations for students on how to succeed in the course

  • Participation is important. Attending lectures is the key to success in this course.
  • Review lecture materials before classes to do well.
  • Reading the recommended literature is obligatory, and will give you a deeper understanding of the material.
