  1. I remember I once wanted to compute tangent of fp64 vectors. Here’s what I did. https://github.com/Const-me/AvxMath/blob/master/AvxMath/AvxM...

  2. …than ideal for the use case. Here’s a better way to implement faster trigonometry functions in C++ https://github.com/Const-me/AvxMath/blob/master/AvxMath/AvxM... That particular source file implements that for 4-wide FP64 AVX vectors.

  3. I once did that as well: https://github.com/Const-me/AvxMath/blob/master/AvxMath/AvxM... The method is different, and the OP hasn’t mentioned it — high-degree minimax polynomial approximation.

  4. BTW, since you apparently working on the stuff like that, check out that repository: https://github.com/Const-me/AvxMath/blob/master/AvxMath/AvxM... The license is MIT, copy-paste friendly. It doesn’t use AVX512 though, only AVX1 and…
