Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
NULL VECTOR::::null vector is avector of zero magnitude and arbitrary direction the sum of a vector and its negative vector is a null vector...
90 degrees
That is usually called the resultant vector.
The zero vector is both parallel and perpendicular to any other vector. V.0 = 0 means zero vector is perpendicular to V and Vx0 = 0 means zero vector is parallel to V.
Adobe Illustrator is a vector based software from adobe creative suite family. Main purpose of it is drawing (vector based objects) but you can work with bitmap images (pictures-pixel based) too. You can do many things with Illustrator, design web page for example, design logos and so on.....
It is a displacement vector.
Resultant vector or effective vector
Vector spaces can be formed of vector subspaces.
A null vector has no magnitude, a negative vector does have a magnitude but it is in the direction opposite to that of the reference vector.
A scalar times a vector is a vector.
Vector addition derives a new vector from two or more vectors, and vector resolution is breaking a vector down into its two or more components.
