SOLUTION: Can you help me find csc0 if cot0 = the - square root of 3 and cos 0 <0
i tried to do cot^20 = (- square root of 3)^2
cot2x= -3
1/tan = -3
1(1/1-sec2x) = (-3)1
1-sec^2x = -3

1-1/cosx = -3
-1/cosx = -2
1(1/cosx) = (-2)1
cosx= -2
But I ended up confusing myself more than getting the answer right. Please help? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! find csc0 if cot0 = -sqrt(3) and cos 0 < 0
----
Note: cot and cos are both negative in QII where x < 0 and y > 0
---------------------------------
Since cot = x/y, x = -sqrt(3) and y = 1
-----
Then r = sqrt[(sqrt(3))^2+1^2] = sqrt[3+1] = 2
--------
Your Problem:
csc(t) = r/y = 2/1 = 2
-----------------------------
