sin 9θ = sin θ ⇒ 9θ = nπ + (-1)n θ
If n = 2m then 9θ = 2mπ + θ ⇒ θ = mπ/4
If n = 2m +1 then 9θ = (2m +1)π - θ
⇒ θ = (2m +1) π/10
The values belonging to [0, π] are

Number of solutions of equation sin 9θ = sin θ in the inte...
The equation sin(99) = sin(x) has infinitely many solutions. This is because the sine function is periodic with a period of 2π. Therefore, for any value of x that is 99 plus a multiple of 2π, the equation will still hold true.
