Course description

The course consists of 


​The schedule, topics and recommended literature (including lecture notes) are given below.


  • Exercise classes: every Wednesday, 14:15-16:00 (F3M01)
    Instructor: Balázs Hetényi

There are 11 sessions involving problem solving, and 2 sessions in which mini-projects are reported. Mini-projects consist of sources on a given topic assigned for homework, which are reported in a short seminar type presentation.


Registration for mini-project presentation (deadline: 13th 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 mini-project.


The whole course is evaluated together with a single mark, given as a combination of the following:  

  • homework: after each of the eleven problem solving classes, the solution of three assigned problems must be submitted. Weight: 30%  
  • mini-project presentation. Weight: 30%
  • written test during the last week of the semester on 24th May (Friday) from 8:00 to 10:00 - 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

0-39: fail (1) 40-54: pass (2) 55-69: average (3) 70-84: good (4) 85-100: excellent (5)

During tests and exams, student can use the following mathematical supplementas well as the summary of calculus in curvilinear coordinates (printed from Wikipedia).
