Find the differentiation of the following:
`(-(1)/(2))`

Explanation

To find the differentiation of the constant function \( y = -\frac{1}{2} \), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Function**:
The given function is \( y = -\frac{1}{2} \). This is a constant function.

2. **Understand Differentiation**:
Differentiation measures the rate at which a function changes. For constant functions, the rate of change is zero because the value does not change regardless of the input.

3. **Apply the Differentiation Rule for Constants**:
The differentiation of any constant \( c \) with respect to \( x \) is given by:
\[ \frac{dy}{dx} = 0 \]
Therefore, for our function:
\[ \frac{dy}{dx} = 0 \]

4. **Conclusion**:
The differentiation of \( y = -\frac{1}{2} \) is:
\[ \frac{dy}{dx} = 0 \]

### Final Answer:
\[ \frac{dy}{dx} = 0 \]
