for 3 quaternions q,r,s; `q**r**s` is one the other is `s**(r**q)` got it. It is just reversing those terms...
Doesn't that then require they also have an account?
So I did this notebook, with a bunch of utility functions dealing with Rotation Vectors... (something like quaternions, but not) I would like to then use these in other notebooks with a minimum of boilerplate... how do I export a set of functions...
Oh I see it now, there is a 'r' referenced internally (again) with another thing I get it. that's not even itself used except when I was trying to debug...
