IN PRESENCE OR VIA ZOOM?

At the moment (20 august 2021) we plan to have "hybrid teaching". Due to the present KTH covid regulations, only 1/3 of the seats can be used in the the lecture rooms. So, some students can attend in presence but most need to attend remotely via zoom:

most of the students will attend the course remotely via zoom. To access the zoom channels, you need a KTH account.

- Zoom link: https://kth-se.zoom.us/j/64088497377
A limited number of seats is available every week to attend in presence ED1110. To attend in presence you need to apply via CANVAS:
- go to "People". You need to be "Registered student", many of you are listed as "admitted but not registered". If you are not registered you might not have access to "people".
- select "Groups". You will see a list of the lectures for the following week.
- press "Join" to the lesson you want to attend in presence.
- If the room is already full, you need to attend the lesson via zoom.
- at this link you can find a short video that show you how to apply to attend in presence ED1110:
- Note that you need to apply EVERY WEEK and for each lesson you want to attend in presence.
- "föreläsningar" will have approximately 30 seats available in presence every week
- "Övningar och lektioner" will have approximately 30 seats (in two rooms) available in presence every week
The application opens each friday at 17:00.
For the first week, the application opens Friday, Aug 27 at 17.00.
BRING YOUR LAPTOP even if you attend in presence

INTRODUKTION

Inom geometrin och mekaniken utgör vektorer (storheter med både storlek och riktning) mycket användbara verktyg. Vidare kan nya vektorer bildas med hjälp av addition, subtraktion, skalärmultiplikation eller kryssprodukt av gamla.

Ibland kan man ha behov av att bestämma hur en vektorstorhet varierar i rummet eller tiden, dvs man intresserar sig för dess derivata. Vektoranalys behandlar just derivator och integraler av vektorer.
Metoderna inom vektoranalysen kan formuleras inom flervariabelsanalysen, men vektoranalysen har mycket större praktisk användbarhet eftersom den tillåter mer komprimerade och intuitiva formuleringar.
Det visar sig att vektoranalys är mycket användbar inom ämnen som teoretisk elektroteknik, vågrörelselära, strömningsmekanik, plasmafysik, gasdynamik och relativitetsteori.

The book used in HT2021:

Since 2019 we use the book:

Title: Vektoranalys
Authors: L. Frassinetti, J. Scheffel
Editor: Liber
ISBN: 978-91-47-12617-0

On the webpage of Liber (see this link) you can download important useful files:

Errata (please, read it carefully. It contains the list of typos and of small errors)
Hints to solve the problems proposed in the book
Full solutions to the problems proposed in the book
Appendix A: practical applications of the basic concepts to electromagnetism.

Before the beginning of the course (HT2021):

It would be very useful if you read the first three chapters of "Vektoranalysis (Frassinetti/Scheffel)" before the lectures of the first week of the course:

Chapter 1: vector algebra (before the lecture of August 30).
Chapter 2: scalar and vector functions (before the lecture of August 30).
Chapter 3: introduction to cylindrical and spherical coordinatesystems (before the lecture of August 31).
Appendix A (available at this link): practical applications (before the lecture of September 2).

In particular, the ED1110 course assume that you are able to work with the following topics and that you have a clear understanding of their geometrical meaning:

sum and subtraction of vectors
scalar product and cross product
absolute value of a vector
projection of a vector in a given direction
basis of a coordinate system
cartesian coordinate system
cylindrical coordinate system
spherical coordinate system

Assignments:

We will have three types of assignments. They are NOT compulsory but they will give points that will help you to pass the exam. See the kurs-PM for details.

Home assignments: one assignment per week. You have approximately one week of time to solve the home assignments. The deadline for the submission is the Monday of the following week at 8am.
Group assignments: one per week, in the last 30min of "övningar". You will divided in groups (or in zoom breakout rooms), with 2-3 students each. You can discuss the solution within your group. But you will have to write and submit your own solution.
Individual assignments: one per week, in the last 30min of "lektion". You have to solve them individually and submit your own solution.

General guidelines for the submission of the assignments:

the submission must be done via CANVAS, even if you are attending in presence.

Use your own sheets to write the solution but write your name in capital letters at the top of the sheet.
- Sheets without name might be disregarded.
For group and individual assignments, if you attend via zoom you must keep camera on (otherwise your assignment will not be graded). We might ask you to keep the microphone on.
Uploading the solution:
- you need to create a pdf file (for example, with the ScanPro app, see the kurs-PM for details).
- We accept only pdf files.
- Please, test the app for creating pdf files several days before your first submission.
- There will be no exceptions to the submission deadlines.
- You need to upload the pdf file with your solution on Canvas.
It is your responsibility to verify that the pdf file with your solution is clear and legible (this implies that also your handwriting must be legible). If the teacher can not read your text, the assignment will be graded with zero points.
The solution is discussed at the beginning of the next class.

If you have questions, feel free to contact me!
See you on August 30.
