inverse oflaplace (s-2)/(s^2-4s+5)

inverse laplace

\frac{s - 2}{s ^{2} - 4 s + 5}

e^{2 t} cos (t)

Solution steps

L^{- 1} {\frac{s - 2}{s ^{2} - 4 s + 5}}

\frac{s - 2}{s ^{2} - 4 s + 5} = \frac{s - 2}{( s - 2 ) ^{2} + 1}

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

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

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

= e^{2 t} cos (t)

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

\int \frac{- 2000 x}{25 - x ^{2}} d x

\frac{d}{d x} (ln (arcsin (x)))

\int - 2 y + 4 e^{- x} d x

\int_{2}^{4} \frac{2 x - 3}{6} d x
