1. The problem statement, all variables and given/known data
4 \ sin \ \theta \ = \ 3 \ csc\ \theta
3. The attempt at a solution
sin\ \theta \ = \ \frac {3}{4} \ csc \ \theta
sin^2 \ \theta \ = \ \frac {3}{4}
sin \ \theta \ = \ \pm \ \frac {\sqrt{3}}{2}
30 \ \deg \ in \ QI, \ 150 \ \deg \ in \ QII, \ 210 \ \deg \ in \ QIII, \ 330 \ \deg \ in \ QIV
Am I doing this correctly?
