### Problem 5: Solving an Integral Equation Using Laplace Transform

**Equation:**  
\[ 
f(t) = \cos t + \int_{0}^{t} e^{-\tau} f(t-\tau) \, d\tau 
\]

**Explanation:**  
This equation involves using the Laplace transform to solve an integral equation where \( f(t) \) is expressed as the sum of a cosine function and a convolution integral. The convolution integral includes an exponential function with decay \( e^{-\tau} \) and the function \( f(t-\tau) \).

**Note:**  
- **\( \tau \)** (tau) is the variable of integration.
