Qualification Goals

The students shall

  • acquire basic knowledge and skills in analysis, in particular an understanding of the concept of limit values for sequences, series, functions and power series,
  • Recognize connections to their own discipline,
  • practice mathematical and in particular analytical ways of thinking and working on concrete questions, also on technically motivated problems,
  • develop mathematical intuition and learn how to translate it into precise terms and formal justifications,
  • to train their abstraction skills,
  • improve their oral communication skills in the exercises by practicing free speech in front of an audience and during discussion
