cscØ = -4

so sinØ = -1/4

we also know that tanØ>0 so

the sine is negative and the tangent is positive ---> Ø must be in III

since sinØ = -1/4, in III, y = -1, r = 4

by Pythagoras and the CAST rule

x = -√15

The rest is now easy, just use your definitions.

let me know what you get.

e.g.

cotØ = x/y = -√15/-1 = √15
