Question

Find the unit vector that has the same direction as the vector v.v = 2i

Answer 1

We have

`\begin{gathered} |v|=\sqrt[]{2^2} \\ |v|=2 \end{gathered}`

We have v=2i

The unit vector that has the same direction is

`(2)/(2)i=i`

The unit vector that has the same direction as the vector v is u=i
