Skolni perlicka: Matematika

Nedavno jsem se ja a moji spoluzaci na hodinach Algebry ucili nekolik zpusobu, jak si zapamatovat vzorec pro vypocet korenu kvadraticke rovnice. Sice jsme to v nas v Cechach ve skole brali jiz pred dlouhou dobou, presto jsem si to rad zopakoval. Nasel jsem totiz v oficialnim pracovnim sesite pro nasi skolu jednu peknou pasaz, jak si vzorec zapamatovat. Pro zopakovani pro jistotu vzorec uvedu, aby vsichni vedeli, o cem je rec:

A nyni vam prozradim ono kouzlo, jak si tenhle vzorecek zapamatovat. Autori moji knizky vymysleli skvelou metodu formou basnicky a pisnicky. Cituji primo z knihy:

Learn this story to help you memorize the Quadratic Formula.

“The negative boy couldn’t decide about going to a radical party. The boy was square and was turned down by four awesome chicks. The party was all over by 2 a.m.”

Vysvětlení: “The negative boy (minus b) couldn’t decide (+, -) about going to a radical (odmocnina z) party. The boy ( b) was square (na druhou) and was turned down (minus) by four (ctyri) awesome (a) chicks (c). The party was all over (to vse deleno) by 2 a (2a) .m.”

Cely text byl pro mene chapajici doplnen poznamkou:

“Or you can sing the Quadratic Formula to the tune of “Jingle Bells“.

No neni to roztomile? 🙂
