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

inverse laplace

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

2 e^{- t} - e^{- t} t

Solution steps

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

Take the partial fraction of

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

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

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

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

= 2 e^{- t} - e^{- t} t

y^{^{'}} = x^{2}

n = 1 \sum \infty \frac{5}{4 ^{n + 1}}

\frac{d}{d x} (cos (6 x^{3}))

(1 + y^{2}) d x + (1 + x^{2}) d y = 0

t - 5
