Ask the student a question, and give any hints about how they should answer this part.
{dragpointa(x[0],y[0])}
Use the diagram above to determine $\sin(\var{angle[0]}^{\circ})$ and $\cos(\var{angle[0]}^{\circ})$. To get to point $A$, we started at $(1,0)$ and rotated by $\var{angle[0]}^{\circ}$. If you hover the mouse over the point $A$, you will be shown its coordinates.
Give your answer to 2 d.p..
$\sin(\var{angle[0]}^{\circ}) =$
$\cos(\var{angle[0]}^{\circ}) =$
