3. What are two ways that a vector can be represented?

Considering a vector in some vector space we have

This is the component form. I don't like that way. It is probably used in high school, but

is preferable because the inner product on is defined to be

You can also write it using linear form such as

4.

For this question, I think you meant

vectors

Once

Considering that the dot product is

and the norm of is

and the norm of is

Thus,

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

the answer is simply just 6n add the two together as they have an n
