Ne ka\u017ed\u00fd s oblibou vzpom\u00edn\u00e1 na \u0161koln\u00ed l\u00e9ta. Prav\u00edtko pat\u0159ilo mezi pom\u016fcky, kter\u00e9 byly d\u016fle\u017eit\u00e9. A\u0165 u\u017e jako pom\u016fcka do geometrie kde jsme si v aktovce tahali r\u016fzn\u00e9 dal\u0161\u00ed \u00faheln\u00edky a nebo pouze klasick\u00e9 prav\u00edtko pro podtr\u017een\u00ed nap\u0159\u00edklad nadpisu nebo data.

Ale v\u00edte co je sinusov\u00e9 prav\u00edtko a k \u010demu se vlastn\u011b pou\u017e\u00edv\u00e1? Pokud se trochu zam\u011b\u0159\u00edme na n\u00e1zev tak si hned m\u016f\u017eeme odvodit, \u017ee n\u00e1zev vznikl od nechvaln\u00e9 funkce sinus s kterou jsme se v\u0161ichni ve \u0161kole setkali.Definici si tady \u0159\u00edkat nebudeme, proto\u017ee by se mohlo st\u00e1t, \u017ee se do toho trochu zamot\u00e1me.
