The given function is:

\[
y = \frac{1}{\sin^2(x)}
\]

To find the derivative of \(y\), we can rewrite it as:

\[
y = (\sin(x))^{-2}
\]

Now, use the chain rule for differentiation:

\[
\frac{dy}{dx} = -2 \cdot (\sin(x))^{-3} \cdot \frac{d}{dx}(\sin(x))
\]

The derivative of \(\sin(x)\) is \(\cos(x)\), so:

\[
\frac{dy}{dx} = -2 \cdot (\sin(x))^{-3} \cdot \cos(x)
\]

This simplifies to:

\[
\frac{dy}{dx} = -\frac{2\cos(x)}{\sin^3(x)}
\]

Thus, the derivative of \(y = \frac{1}{\sin^2(x)}\) is:

\[
\frac{dy}{dx} = -\frac{2\cos(x)}{\sin^3(x)}
\]
