Sine wave

A sine wave, sinusoidal wave, or just sinusoid is a mathematical curve defined in terms of the sine trigonometric function, of which it is the graph. It is a type of continuous wave and also a smooth periodic function. It occurs often in mathematics, as well as in physics, engineering, signal processing and many other fields. (Wikipedia).

A Musician's Intuition on the Fourier Transform (feat. the Inner Product) | 3b1b SoME1

My entry for the 3Blue1Brown Summer of Musical Exposition competition. In this video I describe one way you could derive the Fourier Transform from scratch using trigonometry, numerical simulations, the majesty of the inner product, and no complex numbers. My hope is that this is a somewha

Complex sine waves and interpreting Fourier coefficients

Now that you know the basic mechanics underlying the Fourier transform, it's time to learn about complex numbers, complex sine waves, and how to extract power and phase information from a complex dot product. Don't worry, it's actually not so complex! The video uses files you can download
