## FMA435, 7,5 credits, G1 (First Cycle)

Valid for: 2012/13
Decided by: Education Board 1
Date of Decision: 2011-03-23

## General Information

Main field: Technology.
Compulsory for: Pi1
Language of instruction: The course will be given in Swedish

## Aim

The course aims at giving a basic treatment of calculus in several variables, including three-dimensional vector analysis. Particular emphasis is put on the role which calculus in several variables plays in applications in different subjects of technology, in order to give the future engineer a good foundation for further studies in mathematics as well as other subjects. The aim is furthermore to develop the student's ability in problem solving and to assimilate mathematical text.

## Learning outcomes

Knowledge and understanding
For a passing grade the student must

be able to compute with and handle elementary functions of several variables within the framework of the course, together with their derivatives and integrals, with confidence.

be familiar with different representations of curves, surfaces and volumes in two and three dimensions, and be able to use them in computations.

be able to carry out (specified) changes of variables in partial differential equations, and by this means to solve such equations.

be familiar with the theory of optimization, local as well as global, and be able to find the solution in simple cases.

be able to demonstrate an ability to independently choose methods to evaluate double and triple integrals, and be able to carry out the solution essentially correct.

be able to demonstrate an ability to independently choose methods to evaluate curve and surface integrals, and be able to carry out the solution essentially correct.
