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

inverselaplace

e^{t} sin (t)

Solution steps

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

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

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

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

= e^{t} sin (t)
