Help!!!! (Euclidean three space)

## Homework Statement

Given the Euclidean three space R3and if L is a rotation about the origin, can you prove a situation when L($$\vec{v}$$)=$$\lambda$$ $$\vec{v}$$ and neither lambda or vector v equal zero

## The Attempt at a Solution

I understand that it is a full rotation of 2 pi but I do not know exactly how to prove it.
