inverselaplace (100)/(s(s^2+25))

Lösung

inverse laplace transformation

\frac{100}{s ( s ^{2} + 25 )}

4 H (t) - 4 cos (5 t)

Schritte zur Lösung

L^{- 1} {\frac{100}{s ( s ^{2} + 25 )}}

Ermittle den Partialbruch von

\frac{100}{s ( s ^{2} + 25 )} : \frac{4}{s} - \frac{4 s}{s ^{2} + 25}

= L^{- 1} {\frac{4}{s} - \frac{4 s}{s ^{2} + 25}}

und Konstanten

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{4}{s}} - L^{- 1} {\frac{4 s}{s ^{2} + 25}}

L^{- 1} {\frac{4}{s}} : 4 H (t)

L^{- 1} {\frac{4 s}{s ^{2} + 25}} : 4 cos (5 t)

= 4 H (t) - 4 cos (5 t)
