inverse oflaplace (e^{-4s})/s

inverse laplace

\frac{e ^{- 4 s}}{s}

H (t - 4)

Solution steps

L^{- 1} {\frac{e ^{- 4 s}}{s}}

Apply inverse transform rule:

L^{- 1} {F (s)} = f (t)

then

L^{- 1} {e^{- a s} F (s)} = H (t - a) f (t - a)

Where

H (t)

is Heaviside step function

= H (t - 4) L^{- 1} {\frac{1}{s}} (t - 4)

L^{- 1} {\frac{1}{s}} : H (t)

= H (t - 4) H (t - 4)

= H (t - 4)
