\section{Lösungsidee}
|
||||
Zunächst kann man feststellen, dass der letzte Abschnitt jeder Route zum Bus immer exakt gerade ist. In einer Kurve würde Lisa weiter laufen, ohne am Ende auf der y-Achse weiter zu sein. Es gibt keinen, einen oder zwei Treffpunkte, bei denen Lisa (ohne zu warten) den Bus erwischt:

\begin{proof}
|
||||
Sei Lisa bei $L(x_{L},y_{L})$ und der Bus bei $B(x_{B},y_{B})$. $M(x_{M},y_{M})$ sei der Treffpunkt von Lisa mit dem Bus. $d$ sei der Weg, den Lisa zu diesem Punkt geht.
|
||||
\begin{align*}
|
||||
d &= \sqrt{(x_{L}-x_{M})^2 + (y_{L}-y_{M})^2} &&\text{(Satz des Pythagoras)} \\
|
||||
&= \sqrt{x_{L}^2 + (y_{L}-y_{M})^2} &&\text{($x_{B} = x_{M} = 0$)} \\
|
||||
d^2 &= x_{L}^2 + (y_{L}-y_{M})^2 \\
|
||||
&= x_{L}^2 + (y_{L}-y_{B}-2d)^2 &&\text{($y_{M} = y_{B} + 2d$)} \\
|
||||
&= x_{L}^2 + y_{L}^2 + y_{B}^2 + 4d^2 - 2y_{B}y_{M} - 4dy_{L} + 4dy_{B} \\
|
||||
-3d^2 + 4\cdot(y_{B}-y_{L})\cdot{}d &= x_{L}^2 + y_{L}^2 + y_{B}^2 - 2y_{B}y_{M} \\
|
||||
d &= \frac{a\pm\sqrt{a^2 + 12\cdot{}(-x_{L}^2 - y_{L}^2 - y_{B}^2 + 2y_{B}y_{M})}}{-6} &&\text{($a = 4\cdot(y_{B}-y_{L})$)}\qedhere
|
||||
\end{align*}
|
||||
\end{proof}
|
||||
|
||||
Für diese Gleichung gibt es maximal zwei nicht-negative Lösungen.
