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
Find the top $ S$, the direction $ v$ of the rotation axe and the apex angle $ \alpha$ of the cone

$\displaystyle K: \quad x^2-y^2+z^2+2x-6z+10=0 \; .$

$ S=\Big($ , , $ \Big)$ , $ v=\Big($ , 1 , $ \Big)^{\operatorname t}$ , $ \alpha=$ $ \pi$.

What geometric figure is the section of $ K$ and the plane $ y=1$?
