Form the differential equation of the family of curves `y=Acos2x+Bsin2x ,\ ` where A and B are constants.

Explanation

To form the differential equation of the family of curves given by \( y = A \cos(2x) + B \sin(2x) \), where \( A \) and \( B \) are constants, we will follow these steps:

### Step 1: Differentiate the equation with respect to \( x \)

We start with the equation:
\[ y = A \cos(2x) + B \sin(2x) \]
