Косинус угла

Косинус угла
Косинусом угла α в прямоугольном треугольнике называется отношение прилежащего катета к гипотенузе. Можно дать и такое определение – абсцисса точки B единичной окружности, полученной при повороте точки P(1;0) на угол α. Калькулятор позволяет вычислить косинус угла, зная его значения в градусах или радианах, а также через стороны треугольника.
