Who needs a girlfriend when you have the Fourier Transform? This mathematical marvel transforms your complicated problems into elegant solutions - and unlike your ex, it's never moody!
The Fourier Transform takes those messy time-domain signals and turns them into beautiful frequency spectra. It's basically the Marie Kondo of mathematics - if your differential equation doesn't spark joy, just Fourier Transform it!
Sure, that integral looks intimidating at first glance, but at least it won't text you at 3 AM asking "what are we?" The only commitment issues here are deciding which boundary conditions to use.
