inverselaplace 1/x*(25)/(x^2+25)

Lösung

inverse laplace transformation

\frac{1}{x} \cdot \frac{25}{x ^{2} + 25}

H (t) - cos (5 t)

Schritte zur Lösung

L^{- 1} {\frac{1}{x} \cdot \frac{25}{x ^{2} + 25}}

Schreibe

\frac{1}{x} \frac{25}{x ^{2} + 25}

um:

\frac{25}{x ^{3} + 25 x}

= L^{- 1} {\frac{25}{x ^{3} + 25 x}}

Ermittle den Partialbruch von

\frac{25}{x ^{3} + 25 x} : \frac{1}{x} - \frac{x}{x ^{2} + 25}

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