The function provided is:

\[
f(x) = \frac{e^x + e^{-x}}{2}
\]

To find the derivative \( f'(x) \), we can differentiate this expression.

### Step 1: Rewrite the function
\[
f(x) = \frac{1}{2}(e^x + e^{-x})
\]
This allows us to differentiate each term more easily.

### Step 2: Differentiate each term
Using basic differentiation rules:
- The derivative of \( e^x \) is \( e^x \).
- The derivative of \( e^{-x} \) is \( -e^{-x} \), applying the chain rule.

Thus, the derivative of \( f(x) \) is:
\[
f'(x) = \frac{1}{2} \left( e^x - e^{-x} \right)
\]

This simplifies to:
\[
f'(x) = \frac{e^x - e^{-x}}{2}
\]

### Final Answer:
\[
f'(x) = \frac{e^x - e^{-x}}{2}
\]

This is the derivative of the given function.
