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

Schritte zur Lösung

L {e^{t} t}

Wende Laplace-Transformationstabelle an:

L {t^{k} f (t)} = (- 1)^{k} \frac{d ^{k}}{d s ^{k}} (L {f (t)})

Für

t e^{t} : f (t) = e^{t}, k = 1

= (- 1)^{1} \frac{d}{d s} (L {e^{t}})

L {e^{t}} : \frac{1}{s - 1}

\frac{d}{d s} (\frac{1}{s - 1}) = - \frac{1}{( s - 1 ) ^{2}}

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

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

\frac{d}{d x} (e^{x^{4}} + 7 x)
