WebJul 13, 2024 · The normal vector represents the direction of the plane. But the question was about a line, and the “direction cosines” just mentioned for the unit normal vector show up here, too: A line is specified as the intersection of two nonparallel planes. This means you need two linear equations in x, y, and z to determine a line.
Weba result connecting the direction cosines of any 3-D vector. In 2-D, we have a similar result without the γ term. In 2-D, it is also clear that cos β = ± sin α, so the direction-cosine identity reduces to cos 2 α + sin 2 α = 1. The 3-D result, Eq. (4.9), is a bit less obvious. Example 4.1.2 Direction Cosines. Let A be the column vector 4 2-4.
