Homework Statement
In my study of Quantum Mechanics, I am using Introduction to Quantum Mechanics by David J. Griffiths. So far I have done quite well. However, as I come to the section on Angular Momentum, I need help to get further.
Homework Equations
Classically, the angular momentum of a particle is given by:
[tex] \mathbf{L = r\times p }[/tex]
This is all good. But this is followed by component form of the above equation as:
[tex] L_x = yp_z-zp_y, L_y = zp_x-xp_z, L_z = xp_y-yp_z[/tex]
I am curious how [tex] L_x, L_y , L_x[/tex] are mathematically derived
The Attempt at a Solution
I have look at other textbooks and various posting on internet but I have not been able to find anything to help me with. Hopefully, someone will suggest some thing.
Thanks
