Question:medium
The direction cosines of the straight line given by the planes $x=0$ and $z=0$ are:
The direction cosines of the straight line given by the planes $x=0$ and $z=0$ are:
Show Hint
Geometrically, the intersection of the $yz$-plane ($x=0$) and the $xy$-plane ($z=0$) is the $y$-axis itself. Any line along a coordinate axis has direction cosines where only one component is 1 and the others are 0.
