Таблица котангенсов
Как известно, в прямоугольном треугольнике один угол обязательно прямой, остальные острые. Стороны, прилежащие к углу в 90 градусов, являются катетами треугольника, а сторона, расположенная против прямого угла, — его гипотенуза. Соотношения двух сторон прямоугольного треугольника представляют собой тригонометрические функции. Котангенс острого угла является одной из таких тригонометрических функций. Котангенсом угла является отношение величины прилежащего катета к величине противолежащего катета.
ctg(А) = в / а
где
в — катет, прилежащий углу А;
а — противолежащий катет.
Если известен острый угол прямоугольника, можно найти котангенс угла, воспользовавшись таблицей тригонометрических функций.
Это следует помнить! Если известен угол, вы легко найдете его тригонометрические функции по таблице Брадиса.
Если известны катеты треугольника, можно определить котангенс угла и угол.
Если известен угол и одна из сторон треугольника, можно определить котангенс угла и остальные стороны треугольника.
