Language of instruction: The course will be given in Swedish

The course aims at giving a basic treatment of calculus in several variables. Particular emphasis is given to the role this 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 to solve problems and to assimilate mathematical text.

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 correctly.

be able to demonstrate an ability to independently choose method to evaluate a curve integral, and be able to carry out the solution essentially correctly.

be able to demonstrate a good ability to carry out algebraic calculations within the context of the course.

be able to give a general account of and to illustrate the meaning of such mathematical concepts in calculus in several variables that are used to construct and study mathematical models in the applications.

be able to account for the contents of some central definitions, theorems and proofs.
