Please remember that we have a math-cafe where you can get help with your unsolved exercises (provided you have signed up as described here). Next session is:

- Aalborg: Not scheduled yet.
- Esbjerg: Not scheduled yet.
- Copenhagen: Not scheduled yet.

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.

In this Calculus course we use a BUNDLE OF TWO BOOKS, namely:

- MN: An Introduction to Complex Numbers and Differential Equations", Second Edition, Compiled by Morten Nielsen, Pearson
- E&P: "Calculus: Early Transcendentals", Seventh Edition, Edwards and Penny, Pearson

Abovementioned BUNDLE has ISBN number 9781784499075 and is available in the book store (previously it had ISBN number 1-783-99028-7). The compilation by Morten Nielsen is not sold elsewhere.

In addition, the following material is used:

Please, look at Moodle.

Below you will find suggested exercises for the various Calculus sessions. In case your teacher prepares a separate problem list, please follow that
list. Generally, each student is personally responsible for acquiring sufficient
problem solving skills. A large number of exercises is listed for each session,
so it is recommended that you begin with the 'prioritized' exercises marked with **bold**.
Skills obtained from a given session is often needed for solving the exercises of
subsequent sessions, so therefore it is advisable not to postpone exercises for a given session.

Work is done in your group room.

Program of the day:

- Read Section 10.4, pages 743-749, in E&P regarding Taylor polynomials and Taylors formulas with remainder. You may skip the remarks about infinite sequences at pages 743-744. Start with section "Polynomial Approximations", p. 744.
- Calculate the exercises given below. Although electronic equipments are not allowed to exam, it is still important that engineering students have feelings about numerical calculations. Therefore some of the exercises require calculators (or Matlab or Maple)

Solve the exercises in the given order. Regarding exercise 6 below: The numeric calculations can be done by using calculators. It is also the same for the last exercise.

- Section 10.4, page 755 in E&P: Exercises 1, 3, 4, 13, 16.
- Section 10.4, pages 755 in E&P: Exercises 5, 6.

Write an expression for the general Taylor polynomial of degree `n`

for the function cos(x) expanded around a=0. Write also an expression for the general remainder. Use this to decide an n, such that the four first decimals in the approximation with the value of Taylor polynomial to cos(0.1) is correct.

Note! One shall discuss for the value of `n`

with help of estimates on remainders. It is not enough to make a numerical experiment to decide `n`

. But it is reasonable to make a numerical computation to confirm that one has found a useful value `n`

.

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 recieved a response!**. Please indicate in the email what you need help with (typically jst 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.

The curriculum for the exam can be found under the tab "Curriculum", and the exercises at the exam will be within these topics. It is a good idea to cover the entire curriculum by using the overview of each lecture.

Example: The exercises about curvature are divided into:

- Calculation of arc length.
- Calculation of curvature.
- Determining the time of maximal curvature.
- Determining the tangent and unit normal vectors.
- Determining the circle of curvature.
- Make sure that you can solve exercises of each of these types. Read the examples in the corresponding chapter as well.

*Reflect on the following general principles.*

Which topics are connected/build upon others? Make an overview to yourself, and/or discuss it in your group.

*Remember True/False.*

Use these exercises to figure out the details of the curriculum.

*Then solve previous exam questions* - purpose: To see how the exercises are phrased. To practice the different types of multiple choice questions. Note that exam questions from previous exams which were not multiple choice can easily be relevant; the only difference is the way, the answer is given.

We offer assistance with the exam preparation in both calculus and linear algebra at all three campi. The concept consists of two parts. First, a teacher will solve a number of exercises on the blackboard. Afterwards, there will 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.

Two teaching assistants will be available to help you while you prepare for the exam. They are present in **AUD 6 and 7** on **Tuesday the 12 ^{th} of June** and

Before the re-exam there will be a Q&A-session on **Tuesday the 22 ^{nd} of August** and

There is a Q&A session **Thursday the 14 ^{th} of June** at

Before the re-exam there will be a Q&A-session on **Tuesday the 22 ^{nd} of August** at
