inverse oflaplace 2/((s+1)^3)

inverse laplace

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

e^{- t} t^{2}

Solution steps

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

Apply inverse transform rule:

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

then

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

For

\frac{2}{( s + 1 ) ^{3}} : a = - 1, F (s) = \frac{2}{s ^{3}}

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

L^{- 1} {\frac{2}{s ^{3}}} : t^{2}

= e^{- t} t^{2}

\frac{d}{d x} (- 4 e^{- 2.5 x})

\int sin^{7} (x) d x

\frac{d}{d x} (ln (x + 4))

\int \frac{x ^{2}}{( 2 x + 1 ) ^{5}} d x

\frac{d}{d x} (\frac{x}{1 + e ^{- x}})
