inverse oflaplace 2/(3s^2+6s+2)

inverse laplace

\frac{2}{3 s ^{2} + 6 s + 2}

\frac{2}{3} e^{- t} sinh (\frac{1}{3} t)

Solution steps

L^{- 1} {\frac{2}{3 s ^{2} + 6 s + 2}}

Expand

\frac{2}{3 s ^{2} + 6 s + 2} : \frac{2}{3} \cdot \frac{1}{( s + 1 ) ^{2} - \frac{1}{3}}

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

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

L^{- 1} {\frac{1}{( s + 1 ) ^{2} - \frac{1}{3}}} : e^{- t} 3 sinh (\frac{1}{3} t)

= \frac{2}{3} e^{- t} 3 sinh (\frac{1}{3} t)

Refine

\frac{2}{3} e^{- t} 3 sinh (\frac{1}{3} t) : \frac{2}{3} e^{- t} sinh (\frac{1}{3} t)

= \frac{2}{3} e^{- t} sinh (\frac{1}{3} t)
