The video plots various equations on a coordinate plane—starting with simple linear slopes (f(x)=x) and parabolas (x^2), before moving to exponential growth (e^x) and complex oscillating cosine waves. The pitch of the audio directly corresponds to the height of the graph (the y-value); this means as the line goes up, the sound gets higher,
