$\sin\theta=\frac{y}{r}=\frac{-3}{3}=-1$ $\cos\theta=\frac{x}{r}=\frac{0}{3}=0$ $\tan\theta=\frac{y}{x}=\frac{-3}{0}=undefined$ $\csc\theta=\frac{r}{y}=\frac{3}{-3}=-1$ $\sec\theta=\frac{r}{x}=\frac{3}{0}=undefined$ $\cot\theta=\frac{x}{y}=\frac{0}{-3}=0$

$x=0$ $y=-3$ $r=\sqrt{(-3)^{2}+(0)^{2}}=\sqrt {9+0}= 3$
