    Hello Andrew, :welcome: (welcome back, that is.)

    Not much joy with thread #1, I see. You should know that PF guidelines don't allow help unless an attempt at solution is posted. Least you could do is write down a rotation matrix as described in the problem statement and let it loose on the vector.
