solvefor x,(19)y=(c_{1}+c_{2}x)*e^x

Lösung

löse nach

x, (19) \cdot y = (c_{1} + c_{2} \cdot x) \cdot e^{x}

Lösung

x = W (\frac{19 y e ^{\frac{c _{1}}{c _{2}}}}{c _{2}}) - \frac{c _{1}}{c _{2}}

Schritte zur Lösung

(19) y = (c_{1} + c_{2} x) e^{x}

Schreibe die Gleichung um mit

x + \frac{c _{1}}{c _{2}} = u

und

x = u - \frac{c _{1}}{c _{2}}

19 y = (c_{1} + c_{2} (u - \frac{c _{1}}{c _{2}})) e^{u - \frac{c _{1}}{c _{2}}}

Vereinfache

19 y = e^{u - \frac{c _{1}}{c _{2}}} c_{2} u

19 y = e^{u - \frac{c _{1}}{c _{2}}} c_{2} u

in Lambert-Form umschreiben:

e^{u} u = \frac{19 y e ^{\frac{c _{1}}{c _{2}}}}{c _{2}}

Löse

e^{u} u = \frac{19 y e ^{\frac{c _{1}}{c _{2}}}}{c _{2}} : u = W (\frac{19 y e ^{\frac{c _{1}}{c _{2}}}}{c _{2}})

u = W (\frac{19 y e ^{\frac{c _{1}}{c _{2}}}}{c _{2}})

Setze

u = x + \frac{c _{1}}{c _{2}} w i e d er e in,
