It covers properties of real and rational numbers, mathematical induction, limits of sequences (including the Bolzano-Weierstrass theorem), convergence of series (from basic criteria to the Cauchy multiplication of series), limits and continuity of a function of one variable, properties of continuous functions (intermediate value property, Weierstrass' theorem), convex functions and the notion of a derivative. Full description: 1. Real numbers, infima and suprema of sets, Dedekind's axiom. Natural, integer, rational and irrational numbers, mathematical induction and its applications. 2. Limits of sequences (also infinite), Cauchy's condition, existence of limits of monotone sequences. Existence of n-th roots of positive numbers. Basic techniques for calculating limits, the definition of e. Cesaro-Stolz theorem. Subsequences, Bolzano-Weierstrass theorem. 3. Series of real and complex numbers, convergence of a series. Geometric series, expanding real numbers in numeral systems with different bases. Cauchy's condition for series. Series of non-negative numbers, comparison tests, Cauchy's condensation test, d'Alembert's ratio test, Cauchy's root test. Series of arbitrary numbers - dependence of the series' sum on the order of summation. Alternating series and Leibniz' test. Absolutely convergent series. Abel's and Dirichlet's tests. Cauchy's product of series and its convergence. Irrationality of e. 4. Limit of a function at a point, continuity of a function (Heine's and Cauchy's conditions), intermediate value property. Continuity of the inverse function. Weierstrass' extreme value theorem. Uniform continuity of a continuous function defined on a closed interval. Exponential, logarythmic, trigonometric and cyclometric functions. 5. Convex functions and their geometric interpretation. Jensen's inequality and its consequences: the inequality between arythmetic and geometric means, Schwartz' inequality. Derivative of a function and its basic properties, tangent to the graph of a function. Characterizing convexity in terms of difference quotients and the derivative. Bibliography: 1. A.
