Problem 233: Vector Representation of Geometric Objects


A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

#./aufgabe233_en.tex#Given vectors
$ \vec{a}=$ $ \left(\begin{array}{c}1
\\ 1\end{array}\right)$ and $ \vec{b}=$ $ \left(\begin{array}{r}-1 \\
1\end{array}\right)$.

Which geometric objects are described by the following formulas?

a) $ \vec x= t \vec a + (1-t)\vec b$ ,          $ 0 \leq t \leq 2$
b) $ \vec x = r \vec a + s \vec b$ ,         $ r,s \geq 0$
c) $ \vec x = \vec a \cos t + \vec b \sin t$,          $ 0 \leq t \leq
2 \pi$
