![## 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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F400b9bd7-cb38-477d-bca9-0a4702f014e3%2F4c4e9d46-3f53-46da-b29c-5793d70f9625%2F9gli31d_processed.jpeg&w=3840&q=75)
