It is a fundamental concept in linear algebra and is used to study and manipulate vectors and linear equations.
Are all vector spaces Euclidean? No, not all vector spaces are Euclidean. Euclidean spaces are a specific type of vector space characterized by having an inner product that satisfies certain properties, such as the dot product in three-dimensional Euclidean space (R3). Many vector spaces, such as those in abstract linear algebra, do not have an inner product and are not considered Euclidean.
