Norm and Distance PART 2 | Linear Algebra

Описание: Which vector in two-dimensional space has no corresponding unit vector?
Answer:
Computing a unit vector requires dividing by the magnitude of the original vector. If a vector has magnitude zero, the computation cannot be done. There is only one vector with magnitude zero, and it is 0,0

Find a vector that has the same direction as but has length .
SOLUTION
The given vector has length , so a unit vector in the direction of is .
A vector in the same direction but with length is

Suppose , and .
Compute the following values:
