Solve 2 sin x − 1 = 0 for 0 ≤ x < 2π

Final answer

x = π/6, 5π/6

Solution steps

  1. 1

    Isolate sin x

    sin x = 1/2

  2. 2

    Find the reference angle

    x = π/6

  3. 3

    Sine is positive in quadrants I and II

    x = π/6 or x = 5π/6

Trigonometry study tips

  • Sketch the unit circle; most trig equations come down to reading it.
  • Keep a short list of core identities and try them one at a time.
  • Check whether the problem wants degrees or radians before you answer.

Trigonometry questions

Yes. It answers in whichever unit the problem uses and shows conversions when they're needed.
