WebSep 3, 2024 · We can multiply a vector by a scalar to change its length or give it the opposite direction. Subtraction of vectors is defined in terms of adding the negative of the vector. A vector is written in component form as \(\vecs{v}= x,y \). The magnitude of a vector is a scalar: \(‖\vecs{v}‖=\sqrt{x^2+y^2}\). WebCalculating the magnitude of a vector is only the beginning. The magnitude function opens the door to many possibilities, the first of which is normalization. Normalizing refers to the process of making something “standard” or, well, “normal.”. In the case of vectors, let’s assume for the moment that a standard vector has a length of 1.
