Course detail

# Mathematics 3

FEKT-BPA-MA3Acad. year: 2024/2025

The aim of this course is to introduce the basics of two mathematical disciplines: numerical methods, and probability and statistics.

In the field of probability, main attention is paid to random variables, both discrete and continuous. The end of the course of probability is devoted to hypothesis testing.

In the field of numerical mathematics, the following topics are covered: root finding, systems of linear equations, curve fitting (interpolation and splines, least squares method), numerical differentiation and integration.

Entry knowledge

From the BMA1 and BMA2 courses, the basic knowledge of differential and integral calculus is demanded. Especially, the student should be able to sketch the graphs of elementary functions, to substitute into functions, to compute derivatives (including partial derivatives) and integrals.

Rules for evaluation and completion of the course

For both the tests and the exam you may bring a calculator and maximum 3 pages of A4 format of any notes you like.

Aims

Students completing this course should be able to:

In the field of probability and statistics:

- compute the basic characteristics of statistical data (mean, median, modus, variance, standard deviation)

- choose the correct probability model (classical, discrete, geometrical probability) for a given problem and compute the probability of a given event

- compute the conditional probability of a random event A given an event B

- recognize and use the independence of random events when computing probabilities

- apply the total probability rule and the Bayes' theorem

- work with the cumulative distribution function, the probability mass function of a discrete random variable and the probability density function of a continuous random variable

- construct the probability mass functions (in simple cases)

- choose the appropriate type of probability distribution in model cases (binomial, hypergeometric, exponential, etc.) and work with this distribution

- compute mean, variance and standard deviation of a random variable and explain the meaning of these characteristics

- perform computations with a normally distributed random variable X: find probability that X is in a given range or find the quantile/s for a given probability

- construct estimates of uknown parameters of the known distribution

- estimate parameters of a probability distribution by means of the maximum likelihood method.

In the field of numerical methods, the student should be able to:

- find the root of a given equation f(x)=0 using the bisection method, Newton method or the iterative method, describe these methods including the convergence conditions

- find the root of a system of two equations using Newton or iterative method

- solve a system of linear equations using Gaussian elimination with pivoting, Jacobi and Gauss-Seidel iteration methods, discuss the advantages and disadvantages of these methods

- find Lagrange or Newton interpolation polynomial for given points and use it for approximating the given function

- find the approximation of a function by spline functions

- find the approximation of a function given by table of points by the least squares method (linear, quadratic or exponential approximation)

- choose the most convenient type of approximation (interpolation polynomial, spline, least squares)

- estimate the derivative of a given function using numerical differentiation

- compute the numerical approximation of a definite integral using trapezoidal and Simpson method, describe the principal of these methods, compare them according to their accuracy

- find the approximate solution of a differential equation using Euler method, modified Euler methods and Runge-Kutta methods
