This course builds upon the curriculum from high school. Hence, it is important to be very familiar with this material. If you have the need for repetition, Rob Ghrist's Coursera course 'Calculus 1 variable' may be a good help in addition to revisiting problems from high school.

There will be opened a Teaching Assistant service concerning answers to questions regarding Calculus exercises during the period May 26 to June 5 (including both dates).

Questions may be sent to the following email address: calculushjaelp@math.aau.dk. The number of the exercise that you need help for should be stated as subject, e.g. "Summer examination 2014, exercise 7" or "E&P chapter xxx exercise YYY".

Three teaching assistants are responsible for answering your questions. You may not expect an immediate answer. It depends on the number of questions asked as well as the availability of the teaching assistants.

On Friday June 5 it will be possible to meet one of the teaching assistants in Aalborg. You are to book time via above stated mail address no later than Thursday June 4, at 12 noon. "Subject" should be stated as follows: "Meeting Friday?" and the mail must include a specific question that you need help for and no more than three questions.
