mathswithmuza on Instagram: "The Fourier transform is a mathematical tool that breaks a complicated signal into its basic frequency components, much like taking a piece of music and identifying every pure note that makes it up. Instead of looking at how a function behaves over time or space, the Fourier transform tells you which frequencies are present and how strong they are. This perspective is powerful because many patterns that look messy in the time domain become simple and structured in th
