2010-2011 - REA2041 - 10 ECTS

On the basis of

REA1042 - Mathematics 10 - Functions with one variable

Expected learning outcomes

The students are supposed to:

  • analyse and model problems within classical mechanics, electromagnetism, fluid mechanics and thermal physics
  • evaluate the correctness of their own calculations and work
  • exhibit understanding for relations between theory and practical problems within subjects from electrical, computing, civil and mechanical engineering
