Unformatted text preview: that any two lines lie in a plane, any two vectors in 3dimensional space will also lie in the same plane. This recognition allows us to see that the sum of two vectors will always lie in the plane defined by the original two vectors. As we noted in Vector Subtraction , in order to subtract one vector from another, you simply add its negative partner: u v = u + ( 1) v . Thus, vectors can be subtracted graphically in the same manner used for adding them, by simply taking care to reverse the direction of the vector being subtracted: Figure %: The difference of the vectors u and v in the plane. If you graphically add back in the subtracted vector to your result from the subtraction and you recover the initial vector you subtracted from. In other words, ( u v ) + v = u in our graphical methods, as we should expect!...
