a little question the commutator : [x,p_x] = ? I have my examn next week and I have to know the answer Can someone give me the answer or point me to a good website thnx

I have it in my notes somewhere but it comes from this course:

http://www.ph.ic.ac.uk/ug/course_materials/course.asp?CourseID=19

I don''t know if you''ll find it there (it should be though as he put it on a slide and said they''d all be available for download)

Infact go here and view the powerpoint presentation

http://www.hep.ph.ic.ac.uk/~websdale/web/qm/

we shall say p_x = p for simplicity

[x,p] = xp - px

CPeX,

I know you''ve been around on gamedev.net for a while and most of your questions are definitely appropriate for this site.

However, unfortunately this seems to be a blatant request for the answer to a school related problem, and is inconsistent with the math & physics forum policy on homework questions. Therefore, I must close the thread. For your reference, the forum FAQ can be found at the link below.
