1. Make sure that you study and understand the questions and answers of past quizzes, homework
sets and midterm examinations
2. State the mathematical expression for the Laplace transform of a function
 
ft
The Laplace transform operator involves the following integration
{}=∫ 
0�
3. If the Laplace transform of the function
 
ft
is
 
Fs
and
   
0 0 0ff

, then what is the
Laplace transform of the following functions:
i.
