Step-by-step explanation:
Statement is incomplete. Complete form is presented below:
<em>Let be (6,-3, 1) and (8, 9, -11) vector with same origin. Find the angle between the two vectors. </em>
Let and
, the angle between the two vectors is determined from definition of dot product:
(1)
Where:
,
- Vectors.
,
- Norms of each vector.
Note: The norm of a vector in rectangular form can be determined by either the Pythagorean Theorem or definition of Dot Product.
If we know that and
, then the angle between the two vectors is:
The angle between the two vectors is 84.813°.
