Find the Inverse Laplace of 1/s

We know that the Laplace transform of tn is given by

L{tn} = $\dfrac{n!}{s^{n+1}}$ where n=0, 1, 2, 3, …

Thus, taking the inverse Laplace transform on both sides, we get that

tn = L-1$\left(\dfrac{n!}{s^{n+1}} \right)$

⇒ tn = n! L-1$\left(\dfrac{1}{s^{n+1}} \right)$

Putting n=0 in the above formula, we obtain that

t0 = 0! L-1(1/s)

⇒ 1 = L-1(1/s).

So the inverse Laplace transform formula of 1/s is given by L-1(1/s) = 1, that is, 1 is the inverse Laplace of 1 by s.
