(dx)/(dt)=e^{-kt}

Lösung

\frac{d x}{d t} = e^{- k t}

Lösung

x = - \frac{e ^{- k t}}{k} + c_{1}

Schritte zur Lösung

\frac{d x}{d t} = e^{- k t}

Ersetze

\frac{d x}{d t}

mit

x^{'} (t)

x^{^{'}} (t) = e^{- k t}

Wenn

f^{^{'}} (x) = g (x)

dann

f (x) = \int g (x) d x

x = \int e^{- k t} d t

\int e^{- k t} d t = - \frac{1}{k} e^{- k t} + c_{1}

x = - \frac{1}{k} e^{- k t} + c_{1}

Vereinfache

x = - \frac{e ^{- k t}}{k} + c_{1}
