Vectors are added ‘nose to tail’ as shown below. The addition of the vectors is the line from the starting point to the finishing point. Triangles ABC and XYZ are equilateral. X is the midpoint of AB, ...

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 ...

Back in 1948, the journal Physical Review published a paper entitled “Space-Time Approach to Quantum Electrodynamics” by a young physicist named R.P. Feynman at Cornell University. The paper described ...

The dot product calculator is a free online tool that quickly computes the dot product of given vectors. This tool streamlines the calculation process, providing accurate results in just seconds, ...
