Homework Help: Matrix problem

  1. Jun 10, 2007 #1
    1. The problem statement, all variables and given/known data

    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?
    2. Relevant equations
    3. 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???
