Angular momentum is best expressed as a vector, 1= (L,,!y,lz). In quantum mechanics, the corresponding operators are given by: L = (Îu, Îy, ÎL2), where, (음 i. = -in () Î, = -ih ih ( z- dy (a) Evaluate L,, L, and express your result in terms of Lz. (Hint: In this case, your placcholder function should be f(r, y, z).)
