Aims

After the course the students should understand the main priciples of numeric calculation and the factors influencing calculation. They should be able to solve selected basic problems of numerical analysis, using iteration methods to solve the f(x)=0 equation and systems of linear algebraic equations using calculation algorithms. Theu should learnhow to approximate eigenvalues and eigenvectors of matrices. They should learn about the basic problems in interpolation and approximation of functions solving silple practical problems. Theu should be acquainted with tyhe principles of numeric differentiation and know how to numerically approximate integral of one- and two-functions.
