The solution

You have entered [src]
|sin(x)| < 1
$$\left|{\sin{\left(x \right)}}\right| < 1$$
Abs(sin(x)) < 1
Detail solution
Given the inequality:
$$\left|{\sin{\left(x \right)}}\right| < 1$$
To solve this inequality, we must first solve the corresponding equation:
$$\left|{\sin{\left(x \right)}}\right| = 1$$
Solve:
Given the equation
$$\left|{\sin{\left(x \right)}}\right| = 1$$
transform
$$\left|{\sin{\left(x \right)}}\right| - 1 = 0$$
$$\left|{\sin{\left(x \right)}}\right| - 1 = 0$$
Do replacement
$$w = \left|{\sin{\left(x \right)}}\right|$$
Move free summands (without w)
from left part to right part, we given:
$$w = 1$$
We get the answer: w = 1
do backward replacement
$$\left|{\sin{\left(x \right)}}\right| = w$$
substitute w:

is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
$$x_{0} < x_{38}$$
For example, let's take the point
$$x_{0} = x_{38} - \frac{1}{10}$$
=
$$-98.9601689530982 + - \frac{1}{10}$$
=
$$-99.0601689530982$$
substitute to the expression
$$\left|{\sin{\left(x \right)}}\right| < 1$$
$$\left|{\sin{\left(-99.0601689530982 \right)}}\right| < 1$$
0.995004128836795 < 1

one of the solutions of our inequality is:
$$x < -98.9601689530982$$
