I think it boils down to the alternate view of rotations as two successive reflections. You can then use householder matrix to avoid trigonometry. These geometric math tricks are sometimes useful for efficient computations. For example you can improve Vector-Quantization Variational AutoEncoder (VQ-VAE) using a rotation trick, and compute it efficiently without trigonometry using Householder matrix to find the optimal rotation which map one vector to the other. See section 4.2 of [1] The question why would someone avoid trigonometry instead of looking toward it is another one. Trigonometry…
