What is the inverse Laplace transform of 1 /( s 2?
Determine the inverse Laplace transform of 1/s2. Table 6.1 indicates that the function which has the Laplace transform of 1/s2 is t. Thus the inverse is t. A Laplace transform which is the sum of two separate terms has an inverse of the sum of the inverse transforms of each term considered separately.What is the inverse Laplace transform of 1 /( s 4?
It is equivalent to 1(4?1)- Hence, the inverse Laplace transform of 1 will be 1/s.
