👉 Explementary is a mathematical concept in mathematics, specifically in the field of vector calculus and functional analysis. It refers to the set of vectors that are orthogonal to every vector in the space they span. In other words, it describes the set of all vectors that can be expressed as linear combinations of one or more basis vectors. For instance, consider a vector space V equipped with an inner product (also known as a dot product). Let's say we have two vectors v1 and v2 in V
