 Aims Getting to know the topology of the real axis and the differential and integral calculus of functions of one real variable.
 Content 1. Real valued functions of a real variable. The limit and the continuity of a real function. Discontinuity points. Monotone functions. Darboux functions. Uniformly continuous functions, absolutely continuous functions, and Lipschitz functions. Convex functions. 2. Differential calculus on R. The derivative and the differential of a real function. Operations with differentiable functions. Differentiability of the compound function and of the inverse function. Mean value theorems (Fermat, Rolle, Cauchy, Lagrange). The characterization of a monotone function by the sign of its derivative. Side derivatives. L'Hospital rule. Denjoy-Bourbaki theorem. Higher order derivatives. The characterization of convexity by the sign of derivatives. Taylor formula. Local extrem points of a real function and their characterization by the sign of its derivatives. Functions having primitives. The Darboux property of functions having primitives. 3. Integral calculus of a real function. Divions of a compact interval in R. Properties of Riemann integrable functions. Darboux sums. The lower and the upper integral of a bounded function. Their connection with the Rieman integral. Evaluation of the Riemann integral. Newton-Leibniz formula. Integration by parts and by changing of variable. Rieman-Stieltjes integral and its reduction to Riemann integral. Improprious integral. Their convergence criteria.
