5 credits in mathematics. Participation in Single Variable Calculus. Participation in Linear Algebra and Geometry I or Algebra and Geometry.

## Learning outcomes

On completion of the course the student shall be able to:

• give an account of the concepts of limit, continuity, partial derivative, gradient and differentiability for functions of several variables;
• parametrise curves and surfaces;
• compute partial derivatives of elementary functions;
• use partial derivatives to compute local and global extreme values - with and without constraints;
• outline the definition of the multiple integral, compute multiple integrals and use multiple integrals to compute volumes, centres of gravity, etc.;
• give an account of the concepts of line integral and surface integral and know how to compute such integrals;
• use the theorems of Green, Stokes and Gauss;
• give an account of existence and uniqueness results for solutions to ordinary differential equations, solve simple exact equations and simple linear systems of ordinary differential equations;
• exemplify and interpret important concepts in specific cases;
• formulate important results and theorems covered by the course;
• express problems from relevant areas of applications in a mathematical form suitable for further analysis;
• use the theory, methods and techniques of the course to solve mathematical problems within the course's domain;
• present mathematical arguments to others.

## Instruction

Lectures, lessons and problem solving sessions.

## Assessment

Written examination at the end of the course, or two written tests each of five credit points. Moreover, compulsory assignments may be given during the course in accordance with instructions at the beginning of the course.

If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.

## Other directives

The course cannot be included in passing degree together with the course Several Variable Calculus, limited version.
