## Laplace Transform Exercises

### Problem Statement

2. Find the Laplace transforms of the following functions using the definition:

\[ \mathcal{L}\{f(t)\} = \int_{0}^{\infty} e^{-st} f(t) \, dt. \]

#### Functions

(a) \( f(t) = e^{t+7} \)

(b) \( f(t) = te^{4t} \)

(c) \( f(t) = \cos(4t) \)

### Instructions

For each function, calculate the Laplace transform by substituting into the Laplace transform formula. Show all steps and intermediate calculations to aid understanding.
