Direction Cosine - Formula, Definition, Example - Cuemath
The direction cosine is the cosine of the angle subtended by this line with the x-axis, y-axis, and z-axis respectively. If the angles subtended by the line with the three axes are α, β, and γ, then the direction cosines are Cosα, Cosβ, Cosγ respectively. The direction cosines for a vector → A =a^i +b^j +c ^k A → = a i ^ + b j ^ + c k ...

Direction cosine - Wikipedia
The direction angles a, b and c are acute or obtuse angles, i.e., 0 ≤ a ≤ π, 0 ≤ b ≤ π and 0 ≤ c ≤ π, and they denote the angles formed between v and the unit basis vectors, e x, e y and e z. General meaning. More generally, direction cosine refers to the cosine of the angle between any two vectors.

Cosine error
Cosine error occurs in measuring instrument readings when the user of an instrument does not realize that the vector that an instrument is measuring does The cosine of this triangle correlates to how much error exists in the measurement (hence the name cosine error). wikipedia.org
