(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 ...

Any vector can be expressed as a sum of a number of other vectors. The vectors which are summed are called the components of the original vector. When you want to add and subtract two dimensional ...

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 ...

In this paper, we study the precise large deviations of sums of two-dimensional random vectors with two dependent and real-valued components. In the presence of heavy tails, we obtain some uniformly ...
