5)  (-3, 2)

 

The cosecant  =  r/y       we need to find r  

 

r = sqrt [ (-3)^2 + (2)^2 ]  =   sqrt [ 9 + 4 ]  =   sqrt (13)

 

So    csc  θ   =  √13 / 2

 

6)  (5, -8)

 

Again we need r  =    sqrt [ (5)^2 + (-8)^2 ]  =  sqrt [ 25 + 64]  = sqrt (89)

 

So   csc  P   =  √89 / -8   =  - √89 / 8
