The article concerns the following problem: Given square A B C D with the side of 1. Find points E , F so that the sum l = | A E | + | D E | + | E F | + | B F | + | C F | is the smallest possible. Four solutions are given which are examples of the connection between several mathematical disciplines (geometry, algebra and calculus). The article concludes with a note on the history of the presented problem (leading to P. Fermat and others).

Několik netypických praktických úloh

lánek pojednává o speciálním případu iracionálních rovnic, jejichž jedno řešení lze "snadno uhodnout" a zabývá se otázkami existence a počtu dalších reálných řešení takových rovnic a problematikou jejich nalezení. To je ilustrováno několika konkrétními příklady, při jejichž rozboru jsou využívány různé postupy dostupné též středoškolským studentům.

Několik úvah v souvislosti s projektem mezinárodní srovnávací studie vzdělávání učitelů matematiky

Tomáš Zdráhal, Yanming Wang (2016)

International projects TIMSS, PISA and similar deal with testing pupils' knowledge, among others in mathematics. The public notices their results especially in terms of ranking countries according to their success in these tests. It turns out, however, that the dependence of success in tests on the county, from which pupils come, cannot be proved. Rather, there is a dependence on competence of these pupils' teachers. This competence, however, is difficult to test - both in the Czech Republic and...
