    # Quick trig reminder: suppose we have a triangle ABC, like so:
    #
    #             + B
    #            /|
    #           / |
    #          /  |
    #         /   |
    #        /    |
    #     A +-----+ C
    #
    # Here angle A is 60°, angle B is 30° and angle C is 90° (a right angle).
    #
    # Suppose the length of AB is 1.  Then starting at angle A, we have:
    #
    #       cos(60) = adjacent / hypotenuse
    #               = AC / AB
    #               = AC
    #
    #       sin(60) = opposite / hypotenuse
    #               = BC / AB
    #               = BC
    #
    # So (coordinate1, coordinate2) becomes:
    #
    #       coordinate1 => (x, 0)
    #       coordinate2 => (x cos 60, y sin 60)
    #
    x = coordinate1 + coordinate2 * math.cos(math.radians(60))
    y = coordinate2 * math.sin(math.radians(60))

    return (x, y)
