√1/ [(|x|-1)cos~1(2x+1).tan3x
so buddy we can solve your question by solving your question in parts
so in
 first case :- 
√1/ [(|x|-1)cos~1(2x+1).tan3x ≥ 0

in second case :-
|x|-1 > 0
which means  x²-1>0
(x-1)(x+1)>0
which means we have to use wavy curve method
as shown in figure i made for u in paint
x∈(-∞,-1) ∪ (1 ,∞)
now in third case :-
The domain of the inverse cosine function is [−1,1]
we can use this 
-1≤cosinverse(2x+3) ≤1  but ≠ 0 in any case
so
2x+3≥-1
 x≥-2
and
2x+3= 1
x≤ 1
here we find that  x belongs to [-2,1} but ≠0
and in tan3x domain is R we can take any number now i will put all the parts of x value and the common part will be our answer dude :-
so dude finally we get the domain of the function
x∈ [-2,-1] ∪[1,∞]
