Question

Solve on the interval : [0,2pi]

4 csc x +6=-2


A. 7pi/6 , 11pi/6

B. pi/6 , 5pi/6

C. pi/3 , 5pi/3

D. 2pi/3 , 4pi/3

Answer 1

It is A, the other person is correct. Sorry I am 4 years late answering!

Explanation:

Answer 2

`4\csc{x}+6=-2 \\4\csc{x}=-8 \\ \csc{x}=-2 \\ \\ (1)/(sin(x))=-2 \\ \\ sin(x)=- (1)/(2) \\ \\x= (7\pi)/(6), (11\pi)/(6)`
