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

ℒ{�}=∫ �−

∞

0�

3. If the Laplace transform of the function

ft

is

Fs

and

0 0 0ff
