Informations for semester 2022/23/2
Course description
The course consists of
The schedule, topics and recommended literature (including lecture notes) are given below.

Exercise classes: every Wednesday, 14:1516:00 (F3M01)
Instructor: Balázs Hetényi
There are 9 sessions involving problem solving, and 3 sessions in which miniprojects are reported. Miniprojects consist of sources on a given topic assigned for homework, which are reported in a short seminar type presentation.
Note that there will be a lecture on the 5th of May (which is Friday, but with class schedule for Monday).
Registration for miniproject presentation (deadline: 22nd of March)

Recommended reading:
Course requirements
Condition for signature: attending at least 70% of exercise classes + submission of all homeworks with a score of at least 40% + complete a miniproject.
Evaluation:
The whole course is evaluated together with a single mark, given as a combination of the following:

homework: after the first ten problem solving classes, the solution of three assigned problems must be submitted. Weight: 30%

miniproject presentation. Weight: 30%

written test during the week after the lecture period  includes problem solving and theory. Once the written test has been taken, further exams are oral. Weight: 40%
The results are combined with the weights given above and marked according to
039: fail (1) 4054: pass (2) 5569: average (3) 7084: good (4) 85100: excellent (5)
During tests and exams, student can use the following mathematical supplement, as well as the summary of calculus in curvilinear coordinates (printed from Wikipedia).
