def METHOD_NAME(self, n1: int, n2: int, n3: int) -> float:
    """X-direction cosine of the normal to the plane containing the given nodes.
    X-direction cosine of the normal to the plane containing nodes
    `n1`, `n2`, and `n3`, reported in the global Cartesian
    coordinate system.
    Parameters
    ----------
    n1 : int
        Node number
    n2 : int
        Node number
    n3 : int
        Node number
    Returns
    -------
    float
        X-direction cosine of the normal
    Examples
    --------
    Here we create three nodes in the y-z plane and interrogate the
    x-component of the normal to that plane, which is trivially 1.0.
