solve by convolution theorem
Solution
To solve the given problem using the convolution theorem, let's break it down step by step.
Problem Statement:
You are given a function defined by the integral: and you need to find the Laplace transform using the convolution theorem.
Convolution Theorem:
The convolution theorem states that if , where denotes convolution, then the Laplace transform of is given by: where and are the Laplace transforms of and , respectively.
Step 1: Identify the functions for convolution
The integrand in can be split into two parts: This can be interpreted as the convolution of the following two functions:
Step 2: Find the Laplace transforms of and
- The Laplace transform of is:
- The Laplace transform of is:
Step 3: Apply the Convolution Theorem
