Help!!!! (Euclidean three space)

1. The problem statement, all variables and given/known data

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

2. Relevant equations

3. 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.
