Answer:
x = 0 , π
Step-by-step explanation:
- Rewrite it by using the identity


- Add 4sin x to both the sides.


- Take sin x common from the expression in L.H.S.

Here , we can get two more equations to find x.
1) 
- Divide both the sides by sin x


- Substract 4 from both the sides.



2) 
- Divide both the sides by (sin x + 4)


over interval [0 , 2π).
