Edwards, Penney, Spence, Insel, Friedberg: *Mathematics for Multimedia Applications*,
Compiled by Iver Ottosen Aalborg University, Pearson (2014), ISBN 978-1-78399-714-5

Individual written 4 hours examination. Books and notes are allowed, but no calculators, computers, cell phones or the like.

To be eligible to take the exam, you must have at least 3 accepted self-study assignments (miniprojects) and 10 accepted ordinary hand-in exercises.

Hand-in exercises and miniprojects must be uploaded in Moodle as pdf-files or jpg-files (do not use archive files). Scan in your individual (hand-written) solution or take a picture of it. The file name must include the session number for the hand-in. MATLAB figures can be saved as pdf-files via File -> Save As -> choose pdf format.

There is a deadline for uploading each assignment. After the deadline, the teacher will check a sample of the hand-ins. If an assignment cannot be accepted, the teacher will notify you by email.

Late hand-ins can be uploaded at a special slot, however the teacher can refuse to accept these.

Then the new **Math cafe** is just the right thing for you.
It is held throughout the semester at all three campuses (specific times and places are listed below).
It is an extra possibility for getting help with maths. A teaching assistant is available to help you with exercises from the last few lectures.
The teaching assistants are preparing to help with the material from the last few lectures, and they might not be able to help with all your math questions, but feel free to ask.
This is a new initiative and its success is partly measured by the amount of students coming to the math cafe. If there is a great interest in this initiative we will schedule more than the ones planed now.

**Note:** This is an extra curricular activity, so it is NOT a valid excuse for not participating in other course activities or project work.
