Homework sheets will be posted online Wednesday evening HERE and are due in class on the following Wednesday.

Homework can only be submitted in groups of 2 or 3 students. We expect that these study groups meet regularly to discuss the homework and then each member writes up at least one problem.

To qualify for the final exam, your group has to collect at least 50% of the points awarded in the homework problems.

Final Exam:

15.2.2017, 9 - 11h, Wegelerstr. 10, Großer Hörsaal

To have a look at your graded exam, please come to Endenicher Allee, Room 3.022 on Wed., Feb. 22, 10 - 12h.

Second Exam:
