The matrix is:
cos(pi/3) 0
sin(pi/3) 0
I have no clue what to put. No solution?

Assuming the vector you're given is $(y_1,y_2)^\intercal$, try writing out the multiplication $\left( \begin{array}{cc} \cos{\pi/3} & 0 \\ \sin{\pi/3} & 0 \end{array} \right)\left( \begin{array}{c} x_1 \\ x_2 \end{array} \right)=\left( \begin{array}{c} y_1 \\ y_2 \end{array} \right)$ and describe the set of vectors $(x_1,x_2)^\intercal$ which satisfy that criteria.
