## Homework Statement

Using the irreducible representation of ##su(2)##, with ##j=\frac{5}{2}##, calculate ##J_z##, ##exp(itJ_z)## and ##J_x##.

## Homework Equations

## The Attempt at a Solution

There seem to be loads of irreducible representations of ##su(2)## online, but no reference at all to a specific irreducible representation in my lecture notes. It will be a matrix representation, I suspect, involving something from physics because that's the context we're working in, so maybe the Pauli matrices? I'm completely stuck and any guidance or thoughts on what my lecturer might mean would be very much appreciated! :)
