what are the difference between Co-terminal vector and Co-initial vector?
 
Vectors are the physical quantities which have both direction and magnitude.


 When two or more vectors have the same initial points they are called co-initial vectors.
.
Ex: OA,OB,OC, OD ,OE all these vectors have initial point O. Hence these are co-initial vectors.
Co-terminal vectors :All those vectors whose terminal (end) points are same,such vectors are     called co terminal vectors.                                                  image_thumb31_thumb

Ex: The terminal point of all these vectors \overline{AP},\overline{BP},\overline{CP} ,\overline{DP}   is Same  point P. Hence, these vectors are called co-terminal vectors.
