A PHASE relation familiar to students of applied mathematics exists between a simple harmonic oscillation and its derivative. Similar relations exist between exponential functions and their ...

The equiangular spiral is an example of a simple but fascinating scalar exponential function. The author explains how the scalar exponential can be extended to the multidimensional matrix case to ...
