Negative Frequencies
Explore the concept of negative frequencies in complex sinusoids and how they represent direction in the frequency domain. Understand the relationship between positive and negative frequencies through phase rotation and their significance in digital signal processing.

The idea of a complex sinusoid can easily be extended to discover negative frequencies. This will help us establish the concept of the frequency domain, which we will discuss in detail later.
Direction and negative numbers
Think about negative numbers. They were shrouded in mystery in the early years of mathematical exploration. before it was discovered that they can be associated with the idea of direction.
