Example 3
Find the Inverse Laplace Transform of the following.
7
−1 }
• {
+5
Refer to the expression , so
+
-1
-1
L � 7 � = 7 L � 1 �
+5 +5
= 7 −5
Example 4
Find the Inverse Laplace Transform of the following.
9
{ }
−1
2

L � � = 9 −1 � �
1
-1
2 2
Refer to the expression , and identify the value of n.
n=2,
so,
−1 = 2−1 =
1
( −1)! (2−1)! 1!
1 1
∴ 9 −1 � � = 9 � �
2 1!
= 9
