In the winter semester 2019/2020, Lehrstuhl B für Mathematik is offering the Practical Exercises I.


The Practical Exercises are a supplement to the lectures of the first two semesters. Their purpose is to improve the level of understanding of these lectures. Each week, we publish a work sheet which is to be worked on during that week. Their are small tests about the topics, which are not graded, but have to be passed. Little errors may be corrected in the following week. If a test is not passed, it has to be repeated during the lecture-free period.

In the computer rooms, the are student assistens helping with questions about the worksheets. The exact dates are listed below. For the attestation groups, please register via RWTHonline until 10/11/2019.

Furthermore, it is possible to use the computers in room 242 during the free exercise classes. However, in this classes no student assistents are available.


We use the computer algebra system Maple. Participants may use the computer rooms, where Maple is installed, during the question time. The appopintmensts can be found below.
