Таблица косинусов
Косинусом острого угла считается отношение величины прилежащего катета к величине гипотенузы. Прилежащим является катет, расположенный на одной из сторон угла.
где
в — прилежащий катет; с — гипотенуза.
Косинус является тригонометрической функцией угла. Если нам известна величина угла, мы можем определить косинус угла, воспользовавшись таблицей Брадиса. Если нам известен угол и величина прилежащего катета, можно найти величины других сторон, предварительно определив по таблице косинус угла. Быстро и правильно произвести необходимые вычисления вам поможет онлайн калькулятор.
