inverse oflaplace 1/(((s-1)^2+4))

inverse laplace

\frac{1}{( ( s - 1 ) ^{2} + 4 )}

e^{t} \frac{1}{2} sin (2 t)

Solution steps

L^{- 1} ⎩ ⎨ ⎧ \frac{1}{( ( s - 1 ) ^{2} + 4 )} ⎭ ⎬ ⎫

Apply inverse transform rule:

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

then

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

For

\frac{1}{( s - 1 ) ^{2} + 4} : a = 1, F (s) = \frac{1}{s ^{2} + 4}

= e^{t} L^{- 1} {\frac{1}{s ^{2} + 4}}

L^{- 1} {\frac{1}{s ^{2} + 4}} : \frac{1}{2} sin (2 t)

= e^{t} \frac{1}{2} sin (2 t)

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

y^{^{''}} - 4 y + 4 y = 0

y^{^{'}} = x (2 - y)

x \to - \infty lim (- 3 e^{x})

\frac{d}{d x} (x^{4} - 4 x^{2})
