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

inverse laplace

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

H (t) - e^{- 2 t}

Solution steps

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

Take the partial fraction of

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

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

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

L^{- 1} {\frac{1}{s + 2}} : e^{- 2 t}

= H (t) - e^{- 2 t}

\int \frac{cos ( x )}{( sin ( x ) ) ^{3}} d x

x \to - 7 + lim (\frac{( - 6 x )}{x + 7})

\frac{d ^{2}}{d x ^{2}} (ln (x^{2} + 1))

y^{^{''}} + 6 y^{^{'}} + 9 y = 6 cos (t) + 8 sin (t)

x \to 0 + lim ((1 - 8 x)^{\frac{1}{x}})
