Schritte zur Lösung

L^{- 1} {\frac{10}{16 s ^{2} + 5 s + 1}}

Schreibe

\frac{10}{16 s ^{2} + 5 s + 1}

um:

\frac{5}{8} \cdot \frac{1}{( s + \frac{5}{32} ) ^{2} + \frac{39}{1024}}

= L^{- 1} {\frac{5}{8} \cdot \frac{1}{( s + \frac{5}{32} ) ^{2} + \frac{39}{1024}}}

und Konstante

a : L^{- 1} {a \cdot f (t)} = a \cdot L^{- 1} {f (t)}

= \frac{5}{8} L^{- 1} {\frac{1}{( s + \frac{5}{32} ) ^{2} + \frac{39}{1024}}}

L^{- 1} {\frac{1}{( s + \frac{5}{32} ) ^{2} + \frac{39}{1024}}} : e^{- \frac{5 t}{32}} \frac{32}{39} sin (\frac{39 t}{32})

= \frac{5}{8} e^{- \frac{5 t}{32}} \frac{32}{39} sin (\frac{39 t}{32})

Fasse

\frac{5}{8} e^{- \frac{5 t}{32}} \frac{32}{39} sin (\frac{39 t}{32})

zusammen:

\frac{20 e ^{- \frac{5 t}{32}} sin ( \frac{39 t}{32} )}{39}

= \frac{20 e ^{- \frac{5 t}{32}} sin ( \frac{39 t}{32} )}{39}

\frac{\partial}{\partial x} (x^{2} + 4 y^{2} + 5 z^{2})

f (x) = \frac{7}{10} x^{2} + 4 x^{3}

\frac{d p}{p - p ^{2}} = d t

\frac{d}{d x} (3 x^{4} + 2 x^{3} + x^{2} - 2)
