Question 1035420
I have been given this equation and solution but I am not understanding a specific step in the solution.

CSC theta = -2
solution
    1/sin theta = -2
(do not understand this step)
     sin theta = -1/2

  How does the equation steps look? 
=============
If you want to solve the equation for theta:
CSC theta = -2
1/csc = sin = 1/-2
csc = 1/sin for all angles.
--> sin(theta) = 1/-2 = -1/2
----
You can use a calculator to find theta = -30 degs
--> 330 degrees, or 210 degrees since sine is negative in Q3 and Q4
