I need to find the 5 triq. expressions of $\displaystyle csc=-4$ I know the properties, but I'm not sure which expression I need to start with to find the other 4 expressions.$\displaystyle csc=\frac{1} {sin}$ is sin the receprical of-4, so it will be $\displaystyle sin= \frac{1}{4} $?

Thanks

Jason
