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

The course will be concluded with a 4-hour exam. 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 2 accepted self-study assignments (miniprojects) and 5 accepted ordinary hand-in exercises.

The final exam is a four hour written exam which takes place after the course has finished.

The course is graded using the 7-point scale.

There is a deadline for handing in each assignment. After the deadline, a teaching assistant will check the hand-ins. The corrected hand-in will be returned with comments.

Hand-in exercises and miniprojects must be handed in before the deadline. The hand-in must include your name and the session number for the hand-in. MATLAB figures can be saved as pdf-files via File -> Save As -> choose pdf format.

Then **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.
All you have to do is to **sign up by sending an email to the assistant at least 24 hours before the planned session**. If the assistant hasn't received any email by that time Math Cafe is cancelled without further notice.
**So you can only expect help if you have sent an email in due time and received a response!**. Please indicate in the email what you need help with (typically just a specific exercise) without writing a long email about the details of you problem.

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

Information on when and where the math cafe will take place is coming soon.

Currently the allocated dates **if you have signed up by email** are (will be updated throughout the semester):

- Thursday 7/03-19 16:15-17:45 in Auditorium 1.

We offer assistance with the exam preparation. This consists of a Q&A-session, where it is possible to ask questions within the syllabus and receive help in solving concrete exercises. During this session, it is also possible solve exercises on your own, and then ask for hints if you get stuck. The session takes as its starting point the old exam questions, which may be found here at first.math.aau.dk. We recommend that you solve as many as you can beforehand, such that you know where you come short. Note that the teaching assistants will not visit you in your group rooms. Instead, everyone will be solving exercises individually or in small groups in the rooms specified below.

We urge you to participate from the beginning in order not to disturb during the first part of the session.

There will be a Q&A-session on **Wednesday the 29 ^{th} of May** at

Before the re-exam there will be a Q&A-session on **Friday the 9 ^{th} of August**. Additional information will be added as soon as possible.

A Q&A-session is being planned for the end of May. More details will follow shortly.
