We present an algorithm discovered by Jost Bürgi around 1586, lost until 2013, and proven in 2015. Bürgi’s method needs only sums of integers and divisions by 2 to compute simultaneously and with any desired accuracy the sines of the nth parts of the right angle. We explain why it works with a new proof using polygons and discrete Fourier transforms.
