If is an angle in standard position and its terminal side passes through the point , find theexact value of .
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
