=== Separation
|

==== Statische lösung
|
||||
Möchte man z.b. für $y^' eq 3x^2y plus x^2$ die Statische Lösung so muss man $y^'$ mit 0 ersetzen so das gilt:
|
||||
#grid(columns: (1fr, 1fr), gutter: 10pt, [
|
||||
$ 0 eq 3x^2y plus x^2 $
|
||||
$ 0 eq x^2 dot (3y plus 1) $
|
||||
$ 0 eq 3y plus 1 $
|
||||
$ -1 eq 3y $
|
||||
$ minus frac(1, 3) eq y $
|
||||
$ y(x) eq minus frac(1, 3) $
|
||||
], [
|
||||
Da $x^2$ einen belibigen Wert haben kann kann es ausgeschlossen werden da logischerweise der rest also $0 eq 3y plus 1$ sein muss.
|
||||
])
|
||||
|
||||
|
||||
==== Nicht Statische lösung
|
||||
#grid(columns: (1fr, 1fr), gutter: 10pt, [
|
||||
$ y^' eq x^2 dot y $
|
||||
$ frac(1, y) dot y^' eq x^2 $
|
||||
$ integral frac(1, y) dot y^' dot "dx" eq integral x^2 dot "dx" $
|
||||
$ integral frac(1, y) dot "dy" eq integral x^2 dot "dx" $
|
||||
$ ln(abs(y)) eq frac(1, 3) dot x^3 + c $
|
||||
$ abs(y) eq e^(frac(1, 3) dot x^3 + c) eq e^c dot e^(frac(1, 3) dot x^3) $
|
||||
$ y(x) eq plus.minus e^c dot e^(frac(1, 3) dot x^3) eq C dot e^(frac(1, 3) dot x^3) "mit" C in RR \\ {0} $
|
||||
], [
|
||||
- $y^' eq frac("dy", "dx")$
|
||||
- $integral frac(1, y) dot "dy" eq ln(abs(y))$
