Find the remaining trigonometric ratios.

Question

Hello, 

 

The question is as follows: 

 

Find the remaining trigonometric ratios knowing: csc(θ) = -9/8, 3π/2 < θ < 2π         (π = pi) 

 

I am not sure how to exactly go about the question. I did try but I'm not very confident in my answers. 

 

sin (θ) = -8/9

cos (θ) = sqrt17/9

tan (θ) = -8sqrt17/17 

cot (θ) = 17/-8sqrt17

sec (θ) = 9/sqrt17

 

Any help will be greatly appreciated.
