English level:


All teaching activities will be held in Croatian. However, foreign students in mixed groups will have the opportunity to attend additional office hours with the lecturer and teaching assistants in English to help master the course materials. Additionally, the lecturer will refer foreign students to the corresponding literature in English, as well as give them the possibility of taking the associated exams in English.

The main aim of this course is to make 'connection' between secondary school and faculty mathematics. The students are introduced to basic of mathematical language and ideas. The sets of numbers, functions and relations are considered at the beginning. The second aim is to repeat polynomials (in one and several variables) and fractional rational functions very carefully. A special care will be taken to equations and inequations. A systematic overview of algebraic equations (especially cubic and quartic algebraic equations), rational and irrational equations, equations with modulus, exponential and logarithmic equations, and trigonometric equations, will be done.

1. Introduction. A short overview of history and parts of mathematics. Greek alphabet. Introduction to propositional logic. Propositions. Boolean connectives and complex propositions. Tautologies. Necessary and sufficient condition. The contrapositive. Opposite proposition. Negation of implication.
2. Predicates and quantifiers. Predicates. Universal and existential quantifiers. Negation of quantifiers.
3. Forms of mathematical opinions. Axiomatic construction of mathematical theories. Mathematical notions. Definition of a notion. Theorem and its converse. Fundamental rules of deduction. Basic types of proofs.

7. Functions. The notion of function. Domain and range of function. Inverse of set. Graph. Equality of functions. Restriction and extension of function.
8. Injective and surjective function. Bijection. Permutation. Composition of functions. Inverse of function.
9. Equipotent sets. The notion of equipotent sets. Cardinal numbers. Finite and infinite sets.

12. Fundamental theorem of algebra. Interpolation polynomial. Integer and rational roots of algebraic equations. Complex roots of algebraic equations. Reduciblity and irreducibility of polynomials over the fields C and R. Viete formulas.
