1. The problem statement, all variables and given/known data
Given an axis vector u=（-1, -1, -1) , find the rotational matrix R corresponding to an angle of pi/6 using the right hand rule. Then find R(x), where x = (1,0,-1)

2. Relevant equations
I found the relevant equation on wikipedia (see attachment)
3. The attempt at a solution
I feel that I'm doing something wrong but I don't know what; I think I performed the calculations correctly.

What makes you think something went wrong?
Have you tried testing it, i.e. by applying R to u, or to a vector perpendicular to u, and see if you get the right result?
