inverse oflaplace (s^1)/(s(s^2+s+1))

inverse laplace

\frac{s ^{1}}{s ( s ^{2} + s + 1 )}

Undefined

Solution steps

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

Apply inverse transform rule:

L^{- 1} {F (s)} = f (t)

then

L^{- 1} {s F (s)} = \frac{d}{d t} f (t) + f (0)

For

\frac{s ^{1}}{s ( s ^{2} + s + 1 )} : F (s) = \frac{1}{s ( s ^{2} + s + 1 )}

= \frac{d}{d t} (L^{- 1} {\frac{1}{s ( s ^{2} + s + 1 )}}) + L^{- 1} {\frac{1}{s ( s ^{2} + s + 1 )}} (0)

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

Evaluate

H (t) - e^{- \frac{t}{2}} cos (\frac{3 t}{2}) - \frac{e ^{- \frac{t}{2}} sin ( \frac{3 t}{2} )}{3}

at point

0 =
