Draw the graph of `y = " cosec "^(2) x - cot^(2) x.` Is f(x) periodic ? If yes, what is its fundamental period ?

Explanation

To solve the problem of drawing the graph of \( y = \csc^2 x - \cot^2 x \) and determining if it is periodic, we can follow these steps:

### Step 1: Rewrite the Function
We start with the function:
\[ y = \csc^2 x - \cot^2 x \]
Using the trigonometric identity:
