Differential equations (DGLs): Typing, solution of linear DGL with constant coefficient, initial value problems.

The above topics may be relevant for the exam (s) from July 1st, 2020.

As I said in the lecture, the topics can Derivation of functions, LGS (Gauss), Graph almost as "set" due to their importance for every exam. But of course the other content is also relevant. Just take a good look at the exercises and mock exams. I wish you success!
