(dy)/(dt)=-4y+9e^{-t}

Lösung

\frac{d y}{d t} = - 4 y + 9 e^{- t}

y = \frac{3}{e ^{t}} + \frac{c _{1}}{e ^{4 t}}

Schritte zur Lösung

\frac{d y}{d t} = - 4 y + 9 e^{- t}

Solve linear ODE:

y = \frac{3}{e ^{t}} + \frac{c _{1}}{e ^{4 t}}

y = \frac{3}{e ^{t}} + \frac{c _{1}}{e ^{4 t}}

\int 4 sin^{3} (x) cos^{2} (x) d x
