solvefor u,(d^2u)/(dx^2)=u

Lösung

u, \frac{d ^{2} u}{d f ^{2}} = u

0

Schritte zur Lösung

\frac{d ^{2} u}{d f ^{2}}

\frac{d u}{df} = 0

= \frac{d}{df} (0)

\frac{d}{df} (0) = 0

= 0

16 y^{^{''}} + 8 y^{^{'}} + 5 y = 0

y^{^{''}} + 20 y = 0

(D^{2} + 4 D + 5) y = 0

y^{^{''}} + 4 y^{^{'}} + 4 y = 0, y (0) = 5

y^{^{''''}} + 4 y^{^{'''}} + 6 y^{^{''}} + 4 y^{^{'}} + y = 0
