Solve the given equation over the interval [0, 2π): csc^2 x + 2 csc x = 0.
Anastaziya [24]
csc^2x+2cscx=0
Factor out the GCF which is csc x
cscx(cscx+2)=0
Set each factor equal to zero.
cscx=0  or cscx+2=0
Using the reciprocal sine function we can replace csc in the equations.
\frac{1}{sinx} =0  or \frac{1}{sinx} +2=0
The first equation yields 1 = 0 which is not true. However the second equation does offer 2 possible answers.
When solved for sinx you get 
sinx=- \frac{1}{2}
The sine function is negative in the 3rd and 4th quadrants.
You can use the unit circle or the 
sin^-^1 feature on your calculator  sin^-^1(1/2)
210^o  or 330^o  alter radian answer which is probably what you want is \frac{7 \pi }{6}    or   \frac{11 \pi }{6}
