Factor the trigonometric expression completely. \[ \csc ^{2} w-\tan ^{2} x \] \[ \csc ^{2} w-\tan ^{2} x=(\csc w-\square)(\square+\tan x) \]

Step 1 ：Factor the trigonometric expression completely: \(\csc ^{2} w-\tan ^{2} x\)

Step 2 ：Use the difference of squares formula: \(a^2 - b^2 = (a - b)(a + b)\)

Step 3 ：Apply the formula to the given expression: \(\csc ^{2} w-\tan ^{2} x=(\csc w-\tan x)(\csc w+\tan x)\)

Step 4 ：Final Answer: The factored form of the given trigonometric expression is \(\boxed{(\csc w - \tan x)(\csc w + \tan x)}\)
