TY - JOUR T1 - Minitheory of definite integral A1 - Riečan, Beloslav JA - Obzory matematiky, fyziky a informatiky Y1 - 2014 VL - 43 IS - 1 SP - 25 EP - 37 SN - 1335-4981 N2 - In the paper an elementary theory of the integral f(x) dx for functions f : [a, b] -> R is presented. We use the Riemann construction of the integral, of course, we show that from the practical point of view it is sufficient to consider continuous (partially continuous) functions only. ER -
