Выражение, которое надо упростить:

Решение

Вы ввели [src]
asin(cos(x))
$$\operatorname{asin}{\left(\cos{\left(x \right)} \right)}$$
asin(cos(x))
Подстановка условия [src]
asin(cos(x)) при x = -4
подставляем
asin(cos(x))
$$\operatorname{asin}{\left(\cos{\left(x \right)} \right)}$$
asin(cos(x))
$$\operatorname{asin}{\left(\cos{\left(x \right)} \right)}$$
переменные
x = -4
$$x = -4$$
asin(cos((-4)))
$$\operatorname{asin}{\left(\cos{\left((-4) \right)} \right)}$$
asin(cos(-4))
$$\operatorname{asin}{\left(\cos{\left(-4 \right)} \right)}$$
