Question 3,
![**Problem Statement:**
Find the Laplace transform, \( F(s) \), of the function \( f(t) = \cos(2t) \), where \( t > 0 \).
**Integral Representation:**
\[ F(s) = \int \]
The integral \( F(s) \) stands for the Laplace transform of the function. The integral needs to be completed with appropriate limits and integrand. The drop-down menu suggests selecting the correct differential to integrate with respect to, which is typically \( \text{dt} \) for Laplace transforms.
**Graphical Elements Explanation:**
- **Boxes:** Indicate placeholders for necessary components of the integral, likely including limits and the integrand \( f(t) \times e^{-st} \).
- **Drop-down Menu:** Offers the choice of differential, suggesting options: \( ds \), \( dx \), or \( dt \), with \( dt \) being the correct choice for the Laplace transform.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8e9329bc-2a9a-426c-aebb-7b154c4d8e57%2Facb3515f-1771-4d6c-8922-c365e23b9b8f%2F5vvwnm47_processed.png&w=3840&q=75)
