Determine two angels between 0 degrees and 360 degrees that have a sine ratio of -1/2. Would that be 30 and 330?

  • Calculus -

    so you want sinØ = -1/2
    Then angle must be in quadrants III or IV
    then angle in standard position is 30° (because sin30° = +1/2)

    so our angle is 180+30 = 210° in III
    or our angle is 360-30 = 330 ° in IV

    check by taking sin 210 and sin 330
