Question

2sin^2 theta + sin theta =1

Answer 1

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

2sin^2 theta + sin theta -1 =0
or, 2 sin^2 theta + 2 sin theta - sin theta -1 = 0
or, 2sin theta (sin theta +1) - 1 (sin theta +1) = 0
or, (sin theta +1) (2sin theta -1) =0

either, sin theta +1=0 [solve it urself)
or, 2sin theta -1=0
