# How to find the Inverse Laplace transform of $Exp[(1-s)(1+1/s)]$? [closed]

How do i find the inverse laplace transform of following function:

f[s]=Exp[(1-s)(1+1/s)]


Mathematica returns exactly the simplified function without computing it.

• @MMM Maybe to distinguish it from 50862 and 102042? – QuantumDot Feb 11 '17 at 19:41
• @QuantumDot You are absolutely right! – zhk Feb 11 '17 at 19:43

It works just fine

InverseLaplaceTransform[(1 - s) (1 + 1/s), s, x]


1-δ′(x)

LaplaceTransform[%, x, s]


1/s - s

• Sorry the right function is above – PhysicsExams Feb 11 '17 at 21:52
