Given the inequality:
$$\operatorname{asin}{\left(x - 1 \right)} > \frac{\pi}{6}$$
To solve this inequality, we must first solve the corresponding equation:
$$\operatorname{asin}{\left(x - 1 \right)} = \frac{\pi}{6}$$
Solve:
$$x_{1} = \frac{3}{2}$$
$$x_{1} = \frac{3}{2}$$
This roots
$$x_{1} = \frac{3}{2}$$
is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
$$x_{0} < x_{1}$$
For example, let's take the point
$$x_{0} = x_{1} - \frac{1}{10}$$
=
$$- \frac{1}{10} + \frac{3}{2}$$
=
$$\frac{7}{5}$$
substitute to the expression
$$\operatorname{asin}{\left(x - 1 \right)} > \frac{\pi}{6}$$
$$\operatorname{asin}{\left(-1 + \frac{7}{5} \right)} > \frac{\pi}{6}$$
pi
asin(2/5) > --
6
Then
$$x < \frac{3}{2}$$
no execute
the solution of our inequality is:
$$x > \frac{3}{2}$$
