Questions & Step-by-Step Solutions

If sin(θ) = 0, what are the possible values of θ in the interval [0, 2π]?
Correct Answer: θ = 0, π
  • Step 1: Understand that sin(θ) = 0 means we are looking for angles where the sine function equals zero.
  • Step 2: Recall that the sine function is zero at specific angles on the unit circle.
  • Step 3: Identify the angles in the interval [0, 2π] where sine is zero. These angles are 0 and π.
  • Step 4: Conclude that the possible values of θ in the interval [0, 2π] are θ = 0 and θ = π.
  • Trigonometric Functions – Understanding the values of sine function and its periodic nature.
  • Unit Circle – Using the unit circle to identify angles corresponding to specific sine values.
  • Interval Notation – Recognizing the specified interval [0, 2π] for the solution.
