Course detail

Numerical Methods

FSI-2NUAcad. year: 2011/2012

The course provides an introduction to basic numerical methods frequently used in technical computations. Emphasis is placed on understanding of how numerical methods work. Shorter numerical exercises are carried out with a pocket calculator, but others can be done more efficiently by computers. Main topics: Scientific computing. Systems of linear equations. Interpolation. Least squares method. Numerical differentiation and integration. Nonlinear equations. Optimization.

Learning outcomes of the course unit

Students will be made familiar with a basic collection of numerical methods. They will make sense of errors in mathematical modelling, learn to find zeros of nonlinear equation and to solve systems of linear equations. They will master the basics of approximation including the least squares method, manage to use quadrature formulas and obtain an initial insight into the unconstrained minimization.

Prerequisites

Linear algebra, vector calculus, differential and integral calculus of functions of one variable. Basics of programming.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

COURSE-UNIT CREDIT IS AWARDED ON THE FOLLOWING CONDITIONS: Active participation in practisals. Students have to pass successfully two check tests and to work out semester assignment solved by means of MATLAB, MAPLE, DELPHI and the like, by mutual agreement with the teacher. A student can receive up to 20 points for both tests and up to 10 points for a semester assignment, in total up to 30 points. A necessary condition for course credit acquirement is a gain of at leat 15 points. Students, who reach course-unit credits, thus obtain from 15 to 30 points, which will be included in the final course classification.
FORM OF THE EXAMINATIONS: The exam is written and has a practical and a theoretical part. In the practical part students solve numerical examples by hand using pocked calculator, in the theoretical part they answer several questions to basic notions in order to check up how they understand the subject. As a result of the exam students will obtain 0--70 points.
FINAL ASSESSMENT: The final point course classicifation is the sum of points obtained from both the practisals (15--30) and the exam (0--70).
FINAL COURSE CLASSIFICATION: A (excellent): 100--90, B (very good): 89--80, C (good): 79--70, D (satisfactory): 69--60, E (sufficient): 59--50, F (failed): 49--0.

Aims

The aim of the course is to familiarize students with essential methods applied for solving numerical problems and provide them with an ability to solve such problems individually by hand and especially on computer. Students ought to realize that only the knowledge of substantial features of particular numerical methods enables them to choose a suitable method and an appropriate software product.

Specification of controlled education, way of implementation and compensation for absences

Attendance at lectures is recommended, attendance at seminars is required. Lessons are planned according to the week schedules. Absence from lessons may be compensated by the agreement with the teacher supervising the seminars.
