Form the differential equation representing the family of curves `y = a s in (x + b)`, where a, b are arbitrary constants.

Explanation

To form the differential equation representing the family of curves given by \( y = a \sin(x + b) \), where \( a \) and \( b \) are arbitrary constants, we will follow these steps:

### Step 1: Differentiate the given equation
Start with the equation:
\[ y = a \sin(x + b) \]
Differentiate both sides with respect to \( x \):
...
