Homework Statement
Can anyone help me to proceed with this?
If we execute rotations of 90* about x-axis and 90* about y axis-what is the resulatant rotation matrix?Will the result commute if we rotate by changing the order?Will they commute if infinitesimal rotations are considered?
Homework Equations
The Attempt at a Solution
A qualitative thinking suggest that they will not commute for finite angle but may commute for infinitesimal angles...
...But I possibly cannot visualise the picture correctly.Can anyone refer to some picture?
Most importantly,how to proceed with the calculations?
By the way,what is the rotation matrix for rotation about x,y,z axes?
