Nicht lineare DGL - Riccatti-DGL | Aufgabe mit Lösung

<h2 class="content_heading">Gewöhnliche DGL Lösungsansätze Übersicht</h2>
Separierbare DGL 1. Ordnung 
Form: $y^{\prime}=f(x) \cdot g(y)$
Lösung mithilfe Trennung der Variablen:
$$\int \frac{1}{g(y)} d y=\int f(x) d x$$
 
Durch Substitution lösbare DGL Form: $\mathrm{y}^{\prime}=\mathrm{f}(\mathrm{ax}+\mathrm{by}+\mathrm{c})$ mit $b \neq 0$ Lösung durch Substitution und Trennung der Variablen:
Substituiere: $u=a x+b y+c$, somit ist $y^{\prime}=f(u)$ Dann ist $u^{\prime}=\frac{d u}{d x}=a+b \frac{d y}{d x}=1 \cdot(a+b \cdot f(u))$ Durch Trennung der Variablen erhältst du die Lösung von $u(x)$. Die Rücksubstitution liefert dir dann $y(x)$
 
<h2 class="content_heading">Lineare DGLs</h2>
Die allgemeine Lösung einer inhomogenen linearen DGL setzt sich aus  1. der allgemeinen Lösung $\mathrm{y}_{\mathrm{h}}(\mathrm{x})$ der zugehörigen homogenen DGL 2. der partikulären Lösung $\mathrm{y}_{\mathrm{p}}(\mathrm{x})$ der inhomogenen DGL zusammen:  $\mathrm{y}(\mathrm{x})=\mathrm{y}_{\mathrm{h}}(\mathrm{x})+\mathrm{y}_{\mathrm{p}}(\mathrm{x})$
 
Homogene lineare DGL 1. Ordnung Form: $\mathrm{y}^{\prime}+\mathrm{f}(\mathrm{x}) \cdot \mathrm{y}=0$ Die allgemeine Lösung lautet:
$\mathrm{y}(\mathrm{x})=\mathrm{C} \cdot \mathrm{e}^{-\mathrm{F}(\mathrm{x})}$, wobei $\mathrm{F}(\mathrm{x})=\int \mathrm{f}(\mathrm{x}) \mathrm{d} \mathrm{x}$ und $\mathrm{C} \in \mathrm{R}$.
 
Inhomogene lineare DGL 1. Ordnung Form: $\mathrm{y}^{\prime}+\mathrm{a}(\mathrm{x}) \cdot \mathrm{y}=\mathrm{b}(\mathrm{x})$ Lösung durch Variation der Konstanten:
$\mathrm{y}(\mathrm{x})=\mathrm{c}(\mathrm{x}) \cdot \mathrm{e}^{-\mathrm{A}(\mathrm{x})}$, wobei $c(x)=\int b(x) \cdot e^{+A(x)} d x$ und $\mathrm{A}(\mathrm{x})=\int \mathrm{a}(\mathrm{x}) \mathrm{d} \mathrm{x}$
 
Inhomogene lineare DGL 1. Ordnung mit konstanten Koeffizienten Form: $y^{\prime}+a_{0} y=g(x)$, wobei $a_{0}=konstant$ Allgemeine Lösung der homogenen DGL:
$\mathrm{y}_{\mathrm{h}}(\mathrm{x})=\mathrm{C} \cdot \mathrm{e}^{-\mathrm{a}_{0} \mathrm{x}}$
 
Partikuläre Lösung der inhomogenen DGL: 
<ol>
<li>Wenn $g(x)$ von der Form: $b_{0}+b_{1} x+b_{2} x^{2}+\ldots+b_{n} x^{n}$ Ansatz: $\mathbf{y}_{\mathbf{p}}(\mathbf{x})= c_{o}+c_{1} x+c_{2} x^{2}+\ldots+c_{n} x^{n}$ </li>
<li>Wenn $g(x)$ von der Form: $b \cdot e^{\alpha x}$ und $\alpha \neq-\mathrm{a}_{\mathrm{o}}$ Ansatz: $\mathbf{y}_{\mathbf{p}}(\mathbf{x})=c \cdot e^{\alpha x}$ </li>
<li>Wenn $g(x)$ von der Form: $b \cdot e^{\alpha x}$ und $\alpha=-a_{0}$ Ansatz: $\mathbf{y}_{\mathbf{p}}(\mathbf{x})=c \cdot x \cdot e^{\alpha x}$ </li>
<li>Wenn $g(x)$ von der Form: $b_{1} \cdot \sin (\beta x)+b_{2} \cdot \cos (\beta x)$ Ansatz: $\mathbf{y}_{\mathbf{p}}(\mathbf{x})= c_{1} \cdot \sin (\beta x)+c_{2} \cdot \cos (\beta x)$</li>
</ol>
Die allgemeine Lösung ist dann: $\mathrm{y}(\mathrm{x})=\mathrm{y}_{\mathrm{h}}(\mathrm{x})+\mathrm{y}_{\mathrm{p}}(\mathrm{x})$

<h2 class="content_sub_heading">Allgemeine Lösung einer Riccatischen DGL bestimmen </h2>
Mit gegebener spezieller Lösung $y_{s}(x)$, kannst du die allgemeine Lösung folgendermaßen bestimmen:
<ol>
<li>Setze die Funktion $y(x)=v(x)+y_{s}(x)$ in deine Riccatische DGL ein. Nach einigem Umformen* erhältst du dann:  $\quad v^{\prime}+\left(g(x)+2 h(x) y_{s}(x)\right) \cdot v+h(x) \cdot v^{2}=0$ </li>
<li>Jetzt hast du eine Bernoullische DGL für $v(x)$ und $\alpha=2$. </li>
<li>Ähnlich wie beim Lösen der Bernoulli-DGL transformierst du nun deine DGL mit $v=z^{-1}=\frac{1}{z}$ und erhältst dadurch eine lineare DGL 1. Ordnung für $z$: \begin{align*}\quad z^{\prime}-\left(g(x)+2 h(x) y_{s}(x)\right) \cdot z-h(x)=0\end{align*} </li>
<li>Löse jetzt die lineare DGL 1. Ordnung. Dadurch erhältst du eine Lösung für $z$. </li>
<li>Jetzt setzt du diese allgemeine Lösung für $z(x)$ in die Transformationsgleichungen ein und transformierst zurück: \begin{align*}\quad y(x) &amp;=v(x)+y_{s}(x) =\frac{1}{z(x)}+y_{s}(x) \end{align*}</li>
</ol>

<h2 class="content_sub_heading">Differentialgleichung</h2>
Eine Differentialgleichung (DGL) ist eine Gleichung, die eine Funktion und ihre Ableitungen enthält. Die Lösung einer DGL ist also eine differenzierbare Funktion, die diese Gleichung erfüllt.

<h2 class="content_sub_heading">Kategorien von DGLs</h2>
gewöhnliche DGL: nur Ableitungen von einer Variablen
Beispiel: $y(x) = 4y^{\prime}(x) + y^{\prime \prime}(x)$
 
partielle DGL: mehrere Variablen mit partiellen Ableitungen
Beispiel: $y(x,t) = 4 \frac{\partial^2{y}}{\partial{t^2}} + 3 \frac{\partial{y}}{\partial{x}}$
 
Ordnung: Anzahl der höchsten Ableitung
Beispiel: $y = 4y^{\prime} + y^{\prime \prime}$ (diese DGL ist 2. Ordnung).
 
lineare DGL: nur Linearkombinationen der Funktion und ihrer Ableitungen
Beispiel: $y = 4x^2y^{\prime} + 3xy^{\prime \prime}$
 
nicht-lineare DGL: gesuchte Funktion hat Potenzen oder ist in anderen Funktionen verkettet
Beispiel: $y^{\prime} = sin(y)$
 
homogene DGL: es gibt keinen Term ohne $y$ (die gesuchte Funktion oder ihre Ableitungen)
Beispiel: $y + 2y^{\prime} + 3xy^{\prime \prime} = 0$
 
inhomogene DGL: es gibt Störfunktion (Term ohne $y$)
Beispiel: $y + 2y^{\prime} + 3xy^{\prime \prime} = 2x^2$
 
explizite DGL: höchste Ableitung steht alleine auf einer Seite. (Falls nicht, implizite DGL).
