Question

Solve : sin2 0+ sin 0 = 1 and find 0.​

Answer 1

Answer:

sin2 2x = 0

sin 2x = 0

⇒ 2x = nπ, where, n = 0, ± 1, ± 2, ± 3,……., [Since, we know that θ = nπ, n ∈ Z is the general solution of the given equation sin θ = 0]

⇒ x = nπ2, where, n = 0, ± 1, ± 2, ± 3,…….

Therefore, the general solution of the equation sin2 2x = 0 is x = nπ2, where, n = 0, ± 1, ± 2, ± 3
