1. Real Functions of one Real Variable
The limit and the continuity of a real function of one real variable. The discontinuity points and their classification. Monotonuous functions. Functions with Darboux property. Uniformly continuous functions. Convex functions. 2. Differential Calculus The derivative and the differential of a real function of one real variable. Operations with derivable functions. The derivability of composed functions and of the inverse function. The fundamental theorems of differential calculus ( Fermat's theorem, Rolle's theorem, mean value theorems) and their consequences. The characterisation of the monotony with the help of the derivative. L'Hospital's rule. Higher order derivatives. The characterisation of the convexity with the help of the sign of the second order derivative. Taylor's formula. The characterisation of the optimum points with the help of the derivatives. Primitavible functions. The connection to the Darboux's property. 3. Integral Calculus in R Divisions of a compact, nondegenerat interval in R. The Riemann integrability of a function and the Riemann integral. The connections with the bounderies of a function. Properties of the Riemann integral. Darboux sums. The lower and higher integral of a bounded function. The connection of these with the integrability and the Riemann integral. The calculus of the Riemann integral. Newton-Leibniz's formula. The formula of integration through sides and the formula for the change of the variable. Criteria of Riemann integrability. Classes of Riemann integrable functions. Improper integrals. Criteria for their convergence. The calculus of improper integrals. 4. Sequences and series of functions Continuity, derivability and integrability properties of the limit function of a sequence of functions.
