:Could this be because the article uses a left-handed rotation (as specified on the paragraph giving the matrix for x-y-z convention rotation) ? I'mt not sure, but I think there are a LOT of different ways to convert quaternions to euler angles. See http://www.cgafaq.info/wiki/Euler_angles_from_matrix for example.

:Basically, if someone knowledgeable enough could rewrite the part on conversion to discuss the various possibilities, that would be very nice. [[Special:Contributions/81.63.104.6|81.63.104.6]] ([[User talk:81.63.104.6|talk]]) 20:22, 8 May 2012 (UTC)

:

The final matrix in the "Rotation Matrices" section corresonds to "ZYX" ordering, as per page A-11 of the NASA memo in the references;

I've verified that the expression for the quaternion conforms to the same convention. <span style="font-size: smaller;" class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/50.76.20.17|50.76.20.17]] ([[User talk:50.76.20.17|talk]]) 22:12, 14 January 2014 (UTC)</span><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->

The 'source code' for the quaternion-to-Euler angle conversion doesn’t match the vector representation immediately above it. [[User:SimonJWright|SimonJWright]] ([[User talk:SimonJWright|talk]]) 16:32, 6 December 2016 (UTC)
