The solution
Detail solution
Given the inequality:
$$\sin{\left(t \right)} < \frac{2}{5}$$
To solve this inequality, we must first solve the corresponding equation:
$$\sin{\left(t \right)} = \frac{2}{5}$$
Solve:
Given the equation
$$\sin{\left(t \right)} = \frac{2}{5}$$
transform
$$\sin{\left(t \right)} - \frac{2}{5} = 0$$
$$\sin{\left(t \right)} - \frac{2}{5} = 0$$
Do replacement
$$w = \sin{\left(t \right)}$$
Move free summands (without w)
from left part to right part, we given:
$$w = \frac{2}{5}$$
We get the answer: w = 2/5
do backward replacement
$$\sin{\left(t \right)} = w$$

is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
$$x_{0} < x_{44}$$
For example, let's take the point
$$x_{0} = x_{44} - \frac{1}{10}$$
=
$$-100.119448068806 + - \frac{1}{10}$$
=
$$-100.219448068806$$
substitute to the expression
$$\sin{\left(t \right)} < \frac{2}{5}$$
$$\sin{\left(t \right)} < \frac{2}{5}$$
Then
$$x < -100.119448068806$$
no execute
one of the solutions of our inequality is:
$$x > -100.119448068806 \wedge x < -97.8008891073511$$
Other solutions will get with the changeover to the next point
etc.

$$\sin{\left(t \right)} < \frac{2}{5}$$
To solve this inequality, we must first solve the corresponding equation:
$$\sin{\left(t \right)} = \frac{2}{5}$$
Solve:
Given the equation
$$\sin{\left(t \right)} = \frac{2}{5}$$
transform
$$\sin{\left(t \right)} - \frac{2}{5} = 0$$
$$\sin{\left(t \right)} - \frac{2}{5} = 0$$
Do replacement
$$w = \sin{\left(t \right)}$$
Move free summands (without w)
from left part to right part, we given:
$$w = \frac{2}{5}$$
We get the answer: w = 2/5
do backward replacement
$$\sin{\left(t \right)} = w$$

is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
$$x_{0} < x_{44}$$
For example, let's take the point
$$x_{0} = x_{44} - \frac{1}{10}$$
=
$$-100.119448068806 + - \frac{1}{10}$$
=
$$-100.219448068806$$
substitute to the expression
$$\sin{\left(t \right)} < \frac{2}{5}$$
$$\sin{\left(t \right)} < \frac{2}{5}$$
sin(t) < 2/5
Then
$$x < -100.119448068806$$
no execute
one of the solutions of our inequality is:
$$x > -100.119448068806 \wedge x < -97.8008891073511$$
