I need to find the 5 triq. expressions of I know the properties, but I'm not sure which expression I need to start with to find the other 4 expressions. is sin the receprical of-4, so it will be ?

Thanks

I ignored this in your last thread, but i must say something now. you cannot have trig functions standing alone. writing csc and sin makes no sense! write csc(x) and sin(x) or whatever variable you want, they must be operating on something. that being said, you are right. csc(x) = 1/sin(x)

so if csc(x) = -4, then sin(x) = -1/4

now continue with the others - June 17th 2008, 04:45 PMDarkhrse99
Sorry about that. I'll make sure to write it as Tan (x) as that is the variable we are using.

Sin (x)was so ? Adjacent =

CSC (t) is in the 4th quad, so
