Question 821124: How do you find csc theta in terms of cos theta if theta is in quadrant four ?
I have done the reciprocal identity and changed csc theta to 1/sin, do i use the pythagorean identity sin^2 + cos^2 = 1 ? can you explain to me in detail how to solve this problem ?

----------------
csc = 1/sin
sin%28x%29+=+sqrt%281+-+cos%5E2%28x%29%29
---
csc%28x%29+=+1%2F%28sqrt%281+-+cos%5E2%28x%29%29%29
csc is negative in Q4
