Audio stuff uses different methods depending on the application. Additive oscillators need to be accurate and can use some closed forms and series, mostly people use Taylor and quadratic interpolation as the article shows. For tables remember you only really need to compute amd store one quadrant and shift it around. But for LFOs people use all manner of dirty and quick methods like Bhaskara. https://en.wikipedia.org/wiki/Bhaskara_I%27s_sine_approximation_formula https://en.wikipedia.org/wiki/Bhaskara_I%27s_sine_approximat...
