Как найти косинус одного градуса

Таблица косинусов, найти значения угла косинусов

Косинус угла представляет собой одну из тригонометрических функций. Является соотношением ближнего к углу прямоугольного треугольника катета к гипотенузе. Записывается следующим образом: cos (А) = АС/АВ, где АС – ближний катет угла (А), АВ – гипотенуза.

Зачем необходимо производить такие сложные на первый взгляд вычисления? Еще с древних времен известна аксиома: знаю угол – знаю его тригонометрическую функцию. Соответственно, если известен cos любого угла, в таблице Брадиса можно найти этот угол. И наоборот – зная угол, не сложно вычислить косинус. Отсюда можно найти следующие данные: длина катетов и гипотенузы.

Эти данные используются не только в голых математических вычислениях. Невозможно составить даже элементарный план местности, не зная тригонометрических функций. Посредством онлайн калькулятора можно облегчить задачу и получать требуемые данные за доли секунды.

Косинус угла через градусы, минуты и секунды

Косинус угла через десятичную запись угла

Как найти угол зная косинус этого угла

У косинуса есть обратная тригонометрическая функция – arccos(y)=x

cos(arccos(y))=y

Пример cos(60°) = 1/2; arccos(1/2) = 60°

Рассчитать арккосинус

Определение косинуса

Косинусом острого угла прямоугольного треугольника называется отношение прилежащего катета к гипотенузе.

Косинусом угла α называется абсцисса точки B единичной окружности, полученной при повороте точки P(1;0) на угол α.

Косинус острого угла

cos(α) = AC/AB

cos(-α) = cos(α)

cos(α ± 2π) = cos(α)
