This playlist is a collection of YouTube shorts that are about the imaginary number, defined as the square root of -1.

The square root of -1, a first glance, does not make sense: a number that, multiplied by itself, is equal to -1. However, once we see how useful the idea of the square roots of negative numbers are, we can do a whole bunch more math than ever.

In this playlist, we are looking for solutions to the quadratic function where the square root term is negative.
