**The operators used for the x and y components of angular momentum are:**

Show that Lx and Lz obey an uncertainty relation

Show that Lx and Lz obey an uncertainty relation

**2. No relevant equations.**

## The Attempt at a Solution

I'm going on that the assumption that if LxLy - LyLz does not equal zero then they don't commute and have an uncertainty relation. However I can only get this equal to zero and don't know how to show the uncertainty rrelation if I achieve one.
