inverse oflaplace 2/([(4s^2-8s)])

inverse laplace

\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}

\int \frac{36 - x ^{2}}{x} d x

y^{^{''}} = 36 x^{7} + 21 x^{5} - 3 x + 48 x^{- 5}

sin (x), 1

\frac{d}{d x} (3 sin (2 x) + cos (2 x))

y = x (3 x + 2)^{5}
