I think the idea is that you can eventually get an approximation of whatever wave-like curve you want by merging several pure sin/cos functions with varying amplitudes, wavelengths, and offsets

Fun fact: this is mostly how JPEG works - it uses fourier transforms to approximate an image in a way that takes up much less storage than storing information about each pixel.
