Finding Rotational matrix from axis-angle representation

[fakecop]

Homework Statement

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)

Homework Equations

I found the relevant equation on wikipedia (see attachment)

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.

Please help?http://blob:https%3A//www.physicsforums.com/99c786ac-ed37-4fb2-8cd5-0d1ea0a3afb5

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?
