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.
