Give a general formula of all the solutions

Answer 1

@Vocaloid

Answer 2

start by factoring into:

(2sin(x) + 1) * (sin(x) - 3) = 0

then solve

2sin(x) + 1 = 0
and
sin(x) -3 = 0

use the unit circle if you are stuck

Answer 3

Giving a general for all solutions

Answer 4

Formula

Answer 5

Again, please solve:

2sin(x) + 1 = 0
and
sin(x) -3 = 0

let me know if you are having trouble

Answer 6

You have to give one general formula

Answer 7

That's what I'm trying to do. Again, please solve:

2sin(x) + 1 = 0
and
sin(x) -3 = 0
