Question

Solve the equation for exact solutions over the interval [0, 2x). sin ²x + 2 sinx+1=0 WW Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The sol

Answer 1

Answer: We can rewrite the given equation as:

(sin x + 1)² = 0

Taking the square root of both sides, we get:

sin x + 1 = 0

sin x = -1

The only solution to this equation over the interval [0, 2π) is:

x = 3π/2

Therefore, the correct choice is:

The solution over the interval [0, 2π) is x = 3π/2.
