`sin (ax + b)`

Explanation

To differentiate the function \( y = \sin(ax + b) \) with respect to \( x \), follow these steps:

### Step 1: Identify the function
Let \( y = \sin(ax + b) \).

### Step 2: Apply the chain rule
To differentiate \( y \) with respect to \( x \), we use the chain rule. The chain rule states that if you have a composite function \( f(g(x)) \), then the derivative is given by:
\[
