"""
Returns the Vector after adding it to the Plane.
Parameters
----------
vector Union(Arrow,list,tuple,np.ndarray)
It can be a pre-made graphical vector, or the
coordinates of one.
color (str)
The string of the hex color of the vector.
This is only taken into consideration if
'vector' is not an Arrow. Defaults to YELLOW.
animate (bool=True)
Whether or not to animate the addition of the vector
by using GrowArrow
**kwargs
Any valid keyword argument of Arrow.
These are only considered if vector is not
an Arrow.
Returns
-------
Arrow
The arrow representing the vector.
