$\sin\theta=\frac{y}{r}=\frac{4}{5}$ $\cos\theta=\frac{x}{r}=\frac{-3}{5}$ $\tan\theta=\frac{y}{x}=\frac{4}{-3}$ $\csc\theta=\frac{r}{y}=\frac{5}{4}$ $\sec\theta=\frac{r}{x}=\frac{5}{-3}$ $\cot\theta=\frac{x}{y}=\frac{-3}{4}\cos$

Work Step by Step

$x=-3$ $y=4$ $r=\sqrt{(-3)^{2}+(4)^{2}}=\sqrt {9+16}= 5$
