laplacetransform-4t^2+16t+9

Lösung

laplace transformation

- 4 t^{2} + 16 t + 9

Lösung

- \frac{8}{s ^{3}} + \frac{16}{s ^{2}} + \frac{9}{s}

Schritte zur Lösung

L {- 4 t^{2} + 16 t + 9}

Verwende die lineare Eigenschaft der Laplace-Transformation:

Für Funktionen

f (t), g (t)

und Konstanten

a, b : L {a \cdot f (t) + b \cdot g (t)} = a \cdot L {f (t)} + b \cdot L {g (t)}

= - 4 L {t^{2}} + 16 L {t} + L {9}

L {t^{2}} : \frac{2}{s ^{3}}

L {t} : \frac{1}{s ^{2}}

L {9} : \frac{9}{s}

= - 4 \cdot \frac{2}{s ^{3}} + 16 \cdot \frac{1}{s ^{2}} + \frac{9}{s}

Fasse

- 4 \frac{2}{s ^{3}} + 16 \frac{1}{s ^{2}} + \frac{9}{s}

zusammen:

- \frac{8}{s ^{3}} + \frac{16}{s ^{2}} + \frac{9}{s}

= - \frac{8}{s ^{3}} + \frac{16}{s ^{2}} + \frac{9}{s}
