inverse oflaplace 8/(s^3)

inverse laplace

\frac{8}{s ^{3}}

4 t^{2}

Solution steps

L^{- 1} {\frac{8}{s ^{3}}}

= L^{- 1} {4 \cdot \frac{2}{s ^{3}}}

Use the constant multiplication property of Inverse Laplace Transform:

For function

f (t)

and constant

a : L^{- 1} {a \cdot f (t)} = a \cdot L^{- 1} {f (t)}

= 4 L^{- 1} {\frac{2}{s ^{3}}}

Use Inverse Laplace Transform table:

L^{- 1} {\frac{( n ) !}{s ^{n + 1}}} = t^{n}

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

= 4 t^{2}
