error in Axis-Angle to Euler

You have:
qx*qz = x * z * sin^2(angle/2) = x * z * (1 - cos (angle))

I think that it should be:
qx*qz = x * z * sin^2(angle/2) = x * z * (.5 - .5*cos (angle*2))

That error was propigated down to the simplified version of attitude.

But thank you very much for putting up all your work, your pages have saved me a lot of time!

Thank you very much for this correction.

I am especially grateful because it seems to have simplified the final equations!
I have updated the web page.
