Summary

The aim of the subject is to get acquainted with the basic knowledge of advanced mathematics (linear algebra, in-/definite integral, functions of two variables, differential and difference equations), which is necessary for further studies of quantitative methods in economics. The subject’s structure and nature themselves have their importance as they help to develop logical thinking as well as the ability to enunciate thoughts accurately and to give clear argumentation when solving practical problems.

Requirements for the successful closure of the course - valuation: max. 100 points, min. 51 points. Credit (max. 40 points, min. 20 points) The credit is successfully accomplished if the following conditions are satisfied: 1. Successfully accomplished written test, i.e., at least 50 %. The test will consist of problems presented on the seminars and verifies the computational skills of the student. 2. Completion of all problems submitted by the teacher. Exam (max. 60 points, min. 31 points) 1. The exam is combined and consist of two parts: (a) the written part, (b) the verbal part. 2. The goal of both parts of the exam is the total verification of student's knowledge within the course Mathematics B. In accordance with valid study prescriptions, the student is also requested to apply his mathematical knowledge in practical economic situations. Hence, the written part of the exam will consist of at least one problem associated with applications. Similarly conditions holds for the verbal part. Other concrete requirements will be established by the teacher. 3. The exam is successfully accomplished if the following valuations holds true: (a) written exam: max. 42 points, min. 22 points, (b) verbal exam: max. 18 points, min. 9 points.
