**What are equal vectors?**

Equal vectors are vectors that have the same magnitude and the same direction.

Equal vectors may start at different positions. Note that when the vectors are equal, the directed line segments are parallel.

When are two vectors equal?

Two vectors are equal if they have the same length (magnitude) and direction.

Examples:

1. Let u be the vector represented by the directed line segment from R = (-4, 2) to S = (-1, 6)

a) Find the magnitude of u.

b) Find the component form of the vector.

Equal vectors are vectors that have the same magnitude and the same direction.

Equal vectors may start at different positions. Note that when the vectors are equal, the directed line segments are parallel.

If two vectors are equal then their vector columns are equal.

* Example: *

The column vectors **p** and **q** are defined by

Given that **p** = **q **

a) find the values of *x* and *y*

b) find the values of and

**c) **express *y* in terms of *x*

* Solution: *
