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

is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
$$x_{0} < x_{52}$$
For example, let's take the point
$$x_{0} = x_{52} - \frac{1}{10}$$
=
$$-143.406113347336 + - \frac{1}{10}$$
=
$$-143.506113347336$$
substitute to the expression
$$\left|{\tan{\left(t \right)}}\right| > 2$$
$$\left|{\tan{\left(t \right)}}\right| > 2$$
|tan(t)| > 2

one of the solutions of our inequality is:
$$x < -143.406113347336$$
