TY - JOUR T1 - O Eulerových substitúciách geometricky A1 - Klepancová, Michaela A1 - Varga, Marek JA - Obzory matematiky, fyziky a informatiky Y1 - 2012 VL - 41 IS - 4 SP - 5 EP - 14 SN - 1335-4981 N2 - In the article we deal with Euler’s substitutions as general techniques of integration of irrational functions. Although for finding the indefinite integral of these functions it is sufficient to know their form we go deeper in the understanding of the substitutions and try to interpret their geometrical character. Base on that we derive their form. ER -
