Answer

$\csc$ is the reciprocal of $\sin$

Work Step by Step

1. Sine and cosecant use the same values, just one is the reciprocal of the other. If y is negative, sine and cosecant will be negative; if it is positive, the will both be positive. The value of r will be always positive, because it is a square root. $\sin\theta=\frac{y}{r}$ and $\csc\theta=\frac{r}{y}$
