We saw previously how to represent 2D vectors on the \(xy\) plane. Now, we will extend this to look at 3D vectors using the \(xyz\) plane. 3D coordinates are used, for example, by air traffic ...

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 ...

From trigonometry to calculus and vectors to geometry, few students take A-level mathematics thinking it's going to be an easy subject. But for Daily Mail readers who know their sequences from their ...
