Ответ:

Найдем обратный синус от обеих частей уравнения, чтобы извлечь

x=0,10016742

Функция синуса принимает положительные значения в первом и втором квадрантах. Для определения второго решения вычитаем решение из

π, чтобы найти решение во втором квадранте.

x=(3,14159265)−0,10016742

Упростим выражение, чтобы найти второе решение.

Вычтем

0,10016742 из 3,14159265

x=3,0414252. В данном случае период 2π

x = (-1)' - arcsin 3,14159265 +πn, n€Z.
