Question

Solve trig equation


\( 2 sin^2 \theta + sin \theta =0 \)

What are the solution sets?

Answer 1

factor

Answer 2

let sin = x
so it's same as (2x^2 + x)
now factor

Answer 3

Ah ok thank you. I see not. So it is like \( 2x^2 +1x\) x = sin

Answer 4

yes right x =sin

Answer 5

you got it ?

Answer 6

Yes I got it. Thank you

Answer 7

alright np :-)
