A vector can be represented by a line segment labelled with an arrow. A vector between two points A and B is described as: \(\overrightarrow{AB}\), \(\mathbf{a}\) or \(\underline{a}\). The vector can ...

I have a C++ class for representing 3D coordinates called, say, Vector3. It has four components: X, Y, Z, and W. The fourth component W is always present to make working with homogeneous coordinates ...

It is sometimes important to test the hypothesis that a given set of N unit vectors, representing the directions of a physical quantity, comes from a population of vectors which are randomly oriented ...

(In contrast a scalar quantity has magnitude only - eg, the numbers 1, 2, 3, 4...) The diagram above represents a vector. The arrow displays its direction, hence this ...
