Several messages

Dear all,

Several messages at once:

1. I have decided not to give "interactive lectures" on Wednesdays due to low turnout. Instead, I will hold an extended "office hour" on Wednesdays from 10:15¨C12:00. See Info on digital teaching for up-to-date information.
2. The second mandatory assignment will be published tomorrow, Thursday 16 April, and the deadline is Thursday 30 April at 14:30.
3. I have written a few pages about little-o and big-O notation and its usage for the Fr¨¦chet derivative; see the Syllabus.
4. Videos and quizzes are now located at... drum roll... Videos and quizzes.

Best regards,
Ulrik
