      Hi sorry I don't get your question.
      In the video the final answer is -1/sqrt(3) or can be also written as -sqrt(3) / 3.

    when we shade the area for complex number q, do we use pencil to lightly shade the area? and in q2, do we only shade the blue area in our exam?

      You only need to show the final shaded area that is needed in the question.
