inverse oflaplace 8/(s^4)

inverse laplace

\frac{8}{s ^{4}}

\frac{4 t ^{3}}{3}

Solution steps

L^{- 1} {\frac{8}{s ^{4}}}

= L^{- 1} {\frac{4}{3} \cdot \frac{6}{s ^{4}}}

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)}

= \frac{4}{3} L^{- 1} {\frac{6}{s ^{4}}}

Use Inverse Laplace Transform table:

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

L^{- 1} {\frac{6}{s ^{4}}} = t^{3}

= \frac{4}{3} t^{3}

= \frac{4 t ^{3}}{3}
