    Answer:

    • arctan(1/4)
    • arctan(1/4) -π

    Step-by-step explanation:

    The inverse tangent of 1/4 is an irrational number, only expressible exactly as …

      arctan(1/4)

    This is a first-quadrant angle. There is a matching third-quadrant angle with the same tangent:

      arctan(1/4) -π
