Difference rotating over moving angle and normal angle

Hello,

What is the difference between a moving angle and a normal angle?

Compute the Rotation about Y-axis over moving angle a = 30°

then

rotation about X-axis of angle β= 45°

What will the code like?

Thank you

I think of a normal angle as an absolute attitude and a moving angle as a translational attitude.

absolutePose = rotx(45)*roty(-30)
