def METHOD_NAME(self, k1: int, k2: int, k3: int) -> float:
    """X-direction cosine of the normal to the plane containing the given keypoints.
    X-direction cosine of the normal to the plane containing
    keypoints `k1`, `k2`, and `k3`, reported in the global Cartesian
    coordinate system.
    Parameters
    ----------
    k1 : int
        Node number
    k2 : int
        Node number
    k3 : int
        Node number
    Returns
    -------
    float
        X-direction cosine of the normal
    Examples
    --------
    Here we create three keypoints in the y-z plane and interrogate
    the x-component of the normal to that plane, which is trivially
    1.0.
