Question

what are the possible values for sin theta in:
2sin^2 theta + sin theta -1 = 0

Answer 1

\[2 \sin ^{2} \theta +\sin \theta -1=0\]

Answer 2

\[2 \sin ^{2} \theta + 2 \sin \theta - \sin \theta-1=0\]

Answer 3

\[2 \sin \theta (\sin \theta +1)-(\sin \theta +1)=0\]

Answer 4

\[(2 \sin \theta-1)(\sin \theta +1)=0\]
