Question 845380: Solve the given equation. (Enter your answers as a comma-separated list. Let k be any integer. Round terms to three decimal places where appropriate. If there is no solution, enter NO SOLUTION.)
csc^2 θ = 4 cot θ + 6

You can put this solution on YOUR website!
csc^2 θ = 4 cot θ + 6
-----
(cot^2+1) = 4cot + 6
------
cot^2 - 4cot -5 = 0
------
Factor:
(cot-5)(cot+1) = 0
-----
cot = 5 or cot = -1
----
theta = arctan(1/5) or theta = arctan(-1)
----
t = 11.31 degrees or 191.31 degrees or 135 degrees or 315 degrees
