Differentiate the following :
(ii) `sinx^(3)`

Explanation

To differentiate the function \( y = \sin(x^3) \), we will use the chain rule. The chain rule states that if you have a composite function, the derivative can be found by differentiating the outer function and then multiplying it by the derivative of the inner function.

### Step-by-step solution:

1. **Identify the outer and inner functions**:
- Outer function: \( u = \sin(v) \) where \( v = x^3 \)
- Inner function: \( v = x^3 \)
