inverse oflaplace f(s)= 2/((4s^2-8s))

inverse laplace

f (s) = \frac{2}{( 4 s ^{2} - 8 s )}

- \frac{1}{4} H (t) + \frac{1}{4} e^{2 t}

Solution steps

L^{- 1} {\frac{2}{( 4 s ^{2} - 8 s )}}

Take the partial fraction of

\frac{2}{4 s ^{2} - 8 s} : - \frac{1}{4 s} + \frac{1}{4 ( s - 2 )}

= L^{- 1} {- \frac{1}{4 s} + \frac{1}{4 ( s - 2 )}}

Use the linearity property of Inverse Laplace Transform:

For functions

f (s), g (s)

and constants

a, b : L^{- 1} {a \cdot f (s) + b \cdot g (s)} = a \cdot L^{- 1} {f (s)} + b \cdot L^{- 1} {g (s)}

= - L^{- 1} {\frac{1}{4 s}} + L^{- 1} {\frac{1}{4 ( s - 2 )}}

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

L^{- 1} {\frac{1}{4 ( s - 2 )}} : \frac{1}{4} e^{2 t}

= - \frac{1}{4} H (t) + \frac{1}{4} e^{2 t}

\frac{\partial}{\partial x} (x^{0.6} \cdot y^{0.4})

\int 4 x (x^{2} + 30000)^{- \frac{2}{3}} d x

\int - \frac{2}{x} d x

f (x) = 2 x, (2, 2)

\frac{2}{s ^{2} ( s ^{2} - 2 s + 5 )}
