Kosinusas lentelė, rasti kosinuso kampo reikšmes

Kampo kosinusas yra viena iš trigonometrinių funkcijų. Tai yra gretimo kateto santykis su tiesinio trikampio hipotenuza. Tai užrašoma taip: cos (A) = AC/AB, kur AC – gretimas katetas kampui (A), AB – hipotenuza.

Kodėl būtina atlikti tokias sudėtingas skaičiavimus iš pirmo žvilgsnio? Nuo senovės žinoma aksioma: žinau kampą – žinau jo trigonometrinę funkciją. Atitinkamai, jei cos kampas yra žinomas, šį kampą galima rasti Bradiso lentelėse. Atvirkščiai, – žinant kampą, lengva apskaičiuoti kosinusą. Iš to galima rasti šiuos duomenis: katetų ir hipotenuzos ilgį.

Šie duomenys naudojami ne tik grynai matematiniams skaičiavimams. Be trigonometrinių funkcijų žinojimo negalima nubrėžti net elementaraus ploto plano. Naudojant internetinę skaičiuoklę, užduotis gali būti supaprastinta, o reikiami duomenys gaunami per kelias sekundes.
