**Wording of a question (vectors)**

## Homework Statement

I do not need help for a solution, I only need clarification on the question. I do not understand what the question is asking, here is a picture.

What does it mean when it says the rotation angle alpha? Are x' and y' two different vectors? Also what am I supposed to try to prove? Also what does point P have to do with anything?
