Differentiate w.r.t x
`(x sin x)^(3)`

Explanation

To differentiate the function \( (x \sin x)^3 \) with respect to \( x \), we will follow these steps:

### Step 1: Define the function
Let \( y = (x \sin x)^3 \).

### Step 2: Use the chain rule
To differentiate \( y \) with respect to \( x \), we can use the chain rule. The chain rule states that if \( y = u^n \), then:
\[
