Intended learning outcomes
After passing the course the students should
- have basic knowledge of the theory of ordinary differential equations (ODE),
- be able to solve some types of (systems of) ODEs with standad methods,
- -be able to examine (systems of) ODEs with elementary geometric and with qualitative methods,
- be able to determine Fourier and Laplacetransforms,
- be able to determine the Fourier series representation of periodic continuous-time signals,
- be able to solve separable partial differential equations and determine solutions to boundary value problems with Fourier and transform methods,
- be prepared for deeper studies in fields relevant for their future education,
- be able to use relevant software for solving problems of the type mentioned above with symbolic as well as with geometric methods,
- be able to apply this knowledge of modelling problems.

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
Other requirements for final grade
(TEN1, 6 cr). One examination test,
(INL1, 3 cr), One report.
Opportunity to complete the requirements via supplementary examination
Opportunity to raise an approved grade via renewed examination

Ethical approach
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
