What does it mean to say something is orthogonal?
Definition of orthogonal 1a : intersecting or lying at right angles In orthogonal cutting, the cutting edge is perpendicular to the direction of tool travel. b : having perpendicular slopes or tangents at the point of intersection orthogonal curves.
Where does orthogonal come from?
The word orthogonal comes from the Greek orthogōnios meaning “right-angled.” While this word is used to describe lines that meet at a right angle, it also describes events that are statistically independent, or do not affect one another in terms of outcome.
What is an orthogonal relationship?
Orthogonal lines and mathematics In Euclidean geometry, orthogonal objects are related by their perpendicularity to one another. Lines or line segments that are perpendicular at their point of intersection are said be related orthogonally. Similarly, two vectors are considered orthogonal if they form a 90-degree angle.
What does it mean for two things to be orthogonal?
Definitions. In geometry, two Euclidean vectors are orthogonal if they are perpendicular, i.e., they form a right angle. A term rewriting system is said to be orthogonal if it is left-linear and is non-ambiguous. Orthogonal term rewriting systems are confluent.
What do you mean by orthogonal trajectories?
In mathematics an orthogonal trajectory is a curve, which intersects any curve of a given pencil of (planar) curves orthogonally. For example, the orthogonal trajectories of a pencil of concentric circles are the lines through their common center (see diagram).
What are the orthogonal trajectories of the family of curves?
The orthogonal trajectories are the curves that are perpendicular to the family everywhere. In other words, the orthogonal trajectories are another family of curves in which each curve is perpendicular to the curves in original family.
What is orthogonal in communication?
Orthogonality means both signal is having phase difference of 90 degree. Hence, it will not interfere each other. Just like CDMA, all the channels are orthogonal and hence we can use same frequency allocation for all users but signals are decoded based on PN sequence which is used for spreading the signal.
What are orthogonal skills?
When factors are independent, they can be called orthogonal, fancy for a 90-degree relationship (right angled). They don’t feed each other, they don’t interact, they don’t conflict. Statistically independent: mental ability may be classified into several orthogonal …
Is orthogonal the same as independent?
A group of vectors is independent if no linear combination is zero, or equivalently, no vector is a linear combination of the others. Two nonzero vectors are orthogonal if they are at angle . This implies that the pair are independent.
