• Таблица синусов

    Тригонометрическая окружность наглядно показывает отношения синуса и косинуса при различных значениях угла α. Угол α начинает раскрываться с правой стороны оси косинуса.

    Если исследовать значения синуса, то в первой и второй четверти графика они будут положительны, так как находятся выше оси косинуса, то есть выше нуля, а в третьей и четвертой четверти графика синус станет отрицательным, так как точки окружности опускаются ниже нуля. Поэтому синус угла от до 180° будет со знаком плюс, а синус угла от 180° до 360° будет со знаком минус, как видно из таблицы ниже. В таблице приведены все значения синусов углов от до 360° с точностью до 1 градуса.
