Is |tan x+cot x|<|tan x|+|cot x| true for any x? If it is true,then find the values of x.

( cot x)/( cot x- cot 3x)+ ( tan x)/( tan x- tan 3x)=

The area bounded by the curve f(x)=||tan x+cot x|-|tan x-cot x|| between the lines x=0,x=(pi)/(2) and the X - axis is

If the equation tan (P cot x) = cot (P tan x) has a solution in x in (0, pi) - {(pi)/( 2)} , then
