Possible typo in orientation of reference frames exercise
Thanks for the great content on this course.
I might be wrong, but maybe there's a typo in the exercise that starts with:
[Euler](https://en.wikipedia.org/wiki/Leonhard_Euler) discovered 6 of the 12 orientation sets. One of these sets is shown in this figure
I think where it states
The rightward yellow arrow is the x direction, leftward yellow arrow is the y direction
it should be
the leftward yellow arrow is the x direction, rightward yellow arrow is the y direction
I suspect the solution was done according to the conventions of previous material on the same page, and hence the zxz solution is consistent with the proposed changes.
Otherwise I think the solution would need to change, to be a zyz angle set.
Close this if it's just my misunderstanding.
Thanks!
We did update the figure and I probably didn't update the text properly. I'll have a look. Thanks for reporting.
