|tan(x)| >= \/ 3 
$$\left|{\tan{\left(x \right)}}\right| \geq \sqrt{3}$$
Abs(tan(x)) >= sqrt(3)
Detail solution
Given the inequality:
$$\left|{\tan{\left(x \right)}}\right| \geq \sqrt{3}$$
To solve this inequality, we must first solve the corresponding equation:
$$\left|{\tan{\left(x \right)}}\right| = \sqrt{3}$$
Solve:
Given the equation
$$\left|{\tan{\left(x \right)}}\right| = \sqrt{3}$$
transform
$$\left|{\tan{\left(x \right)}}\right| - \sqrt{3} - 1 = 0$$
$$\left|{\tan{\left(x \right)}}\right| - \sqrt{3} - 1 = 0$$
Do replacement
$$w = \left|{\tan{\left(x \right)}}\right|$$
Expand brackets in the left part
-1 + w - sqrt3 = 0

Move free summands (without w)
from left part to right part, we given:
$$w - \sqrt{3} = 1$$
Divide both parts of the equation by (w - sqrt(3))/w
w = 1 / ((w - sqrt(3))/w)

We get the answer: w = 1 + sqrt(3)
do backward replacement
$$\left|{\tan{\left(x \right)}}\right| = w$$
substitute w:

$$x_{29} = 98.4365698124802$$
$$x_{63} = 99.4837673636768$$
is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
$$x_{0} \leq x_{6}$$
For example, let's take the point
$$x_{0} = x_{6} - \frac{1}{10}$$
=
$$-99.4837673636768 + - \frac{1}{10}$$
=
$$-99.5837673636768$$
substitute to the expression
$$\left|{\tan{\left(x \right)}}\right| \geq \sqrt{3}$$
$$\left|{\tan{\left(-99.5837673636768 \right)}}\right| \geq \sqrt{3}$$
