The solution
Detail solution
Given the inequality:
$$\cos{\left(t \right)} \leq 1$$
To solve this inequality, we must first solve the corresponding equation:
$$\cos{\left(t \right)} = 1$$
Solve:
Given the equation
$$\cos{\left(t \right)} = 1$$
transform
$$\cos{\left(t \right)} - 1 = 0$$
$$\cos{\left(t \right)} - 1 = 0$$
Do replacement
$$w = \cos{\left(t \right)}$$
Move free summands (without w)
from left part to right part, we given:
$$w = 1$$
We get the answer: w = 1
do backward replacement
$$\cos{\left(t \right)} = w$$
substitute w:

is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
$$x_{0} \leq x_{56}$$
For example, let's take the point
$$x_{0} = x_{56} - \frac{1}{10}$$
=
$$-100.530964626003 + - \frac{1}{10}$$
=
$$-100.630964626003$$
substitute to the expression
$$\cos{\left(t \right)} \leq 1$$
$$\cos{\left(t \right)} \leq 1$$
Then
$$x \leq -100.530964626003$$
no execute
one of the solutions of our inequality is:
$$x \geq -100.530964626003 \wedge x \leq -94.2477801171671$$
Other solutions will get with the changeover to the next point
etc.
The answer:
$$x \geq -100.530964626003 \wedge x \leq -94.2477801171671$$
$$x \geq -94.2477797298079 \wedge x \leq -94.2477794452815$$

$$\cos{\left(t \right)} \leq 1$$
To solve this inequality, we must first solve the corresponding equation:
$$\cos{\left(t \right)} = 1$$
Solve:
Given the equation
$$\cos{\left(t \right)} = 1$$
transform
$$\cos{\left(t \right)} - 1 = 0$$
$$\cos{\left(t \right)} - 1 = 0$$
Do replacement
$$w = \cos{\left(t \right)}$$
Move free summands (without w)
from left part to right part, we given:
$$w = 1$$
We get the answer: w = 1
do backward replacement
$$\cos{\left(t \right)} = w$$
substitute w:

is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
$$x_{0} \leq x_{56}$$
For example, let's take the point
$$x_{0} = x_{56} - \frac{1}{10}$$
=
$$-100.530964626003 + - \frac{1}{10}$$
=
$$-100.630964626003$$
substitute to the expression
$$\cos{\left(t \right)} \leq 1$$
$$\cos{\left(t \right)} \leq 1$$
cos(t) <= 1
Then
$$x \leq -100.530964626003$$
no execute
one of the solutions of our inequality is:
$$x \geq -100.530964626003 \wedge x \leq -94.2477801171671$$
