INL1 – Homework assignments, 2.0 credits
The course includes three compulsory homework assignments. Each assignment may be completed individually or in a self-selected group of two students. Each group submits one written report in Canvas.
Reports submitted by the following deadlines make the members of the group eligible for bonus points on the written examinations during the academic year 2026/2027:
- Homework assignment 1, 1 bonus point: Tuesday, 10 November 2026
- Homework assignment 2, 1 bonus point: Tuesday, 24 November 2026
- Homework assignment 3, 2 bonus points: Friday, 11 December 2026
A passing result for INL1 remains valid. Students who have already passed INL1 may not resubmit the homework assignments and are not eligible to earn new bonus points in a later course offering.
Regardless of bonus points, all three reports must be submitted by Friday, 11 December 2026 to be assessed in connection with the January examination. If a report submitted by this date is not accepted, the group may submit a revised report no later than the date of the January examination.
Reports may also be submitted by the date of the re-examination. A student who has not completed all three homework assignments by that date will be referred to the next course offering.
The homework assignments are intended to develop the ability to apply mathematical concepts and methods and to communicate mathematical work in writing. A report should explain the problem, provide the necessary theoretical background, and present the results at a level suitable for a student who has completed SF1811 but has not worked on the particular assignment.
The report should be written in the students' own words and should explain the main steps of the solution. The style may be similar to that used for examples in the course literature. A report will normally be no longer than five pages. The precise format is not important. The essential requirements are mathematical correctness, clarity, and sufficient explanation for the intended reader.
Any use of generative AI must be declared in the report, as described in the separate section on the use of generative AI.
TEN2 – Written examination, 4.0 credits
The written examination consists of five questions worth 10 points each, giving a maximum examination score of 50 points. Up to four bonus points from the homework assignments may be added to the examination score. A total score of at least 25 points, including bonus points, is required for a passing grade. The normal grade thresholds, including bonus points, are: E: 25 points; D: 29 points; C: 34 points; B: 39 points; A: 45 points.
One of the five examination questions assesses mathematical argumentation and understanding of theory. The question consists of two independently assessed parts: (a) formulation and proof, or derivation, of one of the announced theory results, worth 5 points; and (b) use or interpretation of the result in a related situation that is not announced in advance, worth 5 points. In part (b), the stated theory result may be used without proof.
The announced theory results and further information about the question are available in Canvas.
The grade Fx is normally given to a student who has obtained 21–24 points on the written examination itself but has not reached 25 points after bonus points have been added.
An Fx grade may be converted to an E grade through successful completion of two supplementary exercises: one concerning a theory result from the announced list and one concerning a computational or methodological part of the examination. Both exercises must be completed independently, submitted in writing, and explained orally. As in the theory question on the written examination, the oral explanation of the theory exercise includes a related part (b) that is not announced in advance.
The supplementary exercises are selected individually by the examiner based on the knowledge and skills that the student did not demonstrate sufficiently in the examination. It is the student's responsibility to contact the examiner to initiate the supplementary examination. The supplementary examination must be completed within three weeks of the date on which the student was notified of the grade.
The examination questions are written in English. Answers may be written in English or Swedish. No aids are permitted except pens, pencils, an eraser, and a ruler. Calculators and dictionaries are not permitted. The formula sheet available in Canvas will be provided with the examination.
The written examination is scheduled for Monday, 11 January 2027, 08:00–13:00. Students must register in advance in accordance with KTH's examination registration rules.
