Find the derivatives of the following (1-3) functions :
`f(x) = pi`

Answer

To find the derivative of the function \( f(x) = \pi \), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the function**:
The function given is \( f(x) = \pi \). Here, \( \pi \) is a constant.

2. **Recall the derivative of a constant**:
The derivative of any constant function is always 0. This is because a constant function does not change as \( x \) changes.

3. **Apply the derivative rule**:
Since \( f(x) \) is a constant function, we can state that:
\[ f'(x) = 0 \]

4. **Write the final answer**:
Therefore, the derivative of the function \( f(x) = \pi \) is:
\[ f'(x) = 0 \]

### Final Answer:
\[ f'(x) = 0 \]
