tan|x| = |tanx| possible values of x is ?Plzz answer urgently

it is true for all values of x .

just check by graph . i can tell how to draw the graph of these 2 seperate function and you just need to check the intersection between 2 curves. 

for tan|x| or for general g(|x|).

step 1 :  draw graph of g(x).

step 2:  just remove left part of graph and then take reflection of right half considering y axis as mirror.

for |tanx| or for general |f(x)|.

step 1 : draw graph of f(x).

step 2 : just take reflection of graph below x axis cosidering x axis as mirror and then remove the lower part of graph.

now watch for intersection berween two graphs .

and hence watch for values of x . 

actually its just by chance that both the graph are same so there are infinite number of intersection .
