В таблице тангенсов и котангенсов приведены значения этих тригонометрических функций для углов от 0 до 360 градусов. Для расчета значений
тангенсов и котангенсов для углов с минутами и секундами или отрицательных углов (например 19° 15′ 44″ или - 485° 27′ 34″ )
можно воспользоваться тригонометрическим калькулятором.
