inverse oflaplace (e^{-2s})/(s+3)

inverse laplace

\frac{e ^{- 2 s}}{s + 3}

H (t - 2) e^{- 3 (t - 2)}

Solution steps

L^{- 1} {\frac{e ^{- 2 s}}{s + 3}}

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 - 2) L^{- 1} {\frac{1}{s + 3}} (t - 2)

L^{- 1} {\frac{1}{s + 3}} : e^{- 3 t}

= H (t - 2) e^{- 3 (t - 2)}
