Which of the following represents the correct way to express the square of the sine function?
Which of the following represents the correct way to express the square of the sine function?
- sin² θ = sin(sin θ)
- sin² θ = (sin θ) - (sin θ)
- sin² θ = sin θ * sin θ (correct)
- sin² θ = (sin θ) + (sin θ)
