Question

let v1=(3,5) and v2=(-4,7)
Compute the unit vectors in the direction of |v1| and |v2|????

Answer 1

unit vector v1= \[\frac{ v1 }{ ||v1|| }\] just compute. that's it

Answer 2

So you would put (3,5) on top and what on the bottom then?

Answer 3

sorry, I messed up the denominator, let me redo

Answer 4

Is it the v2 on the bottom then?

Answer 5

\[\frac{ <3,5> }{ \sqrt{3^2 + 5^2} }= \frac{ <3,5> }{ \sqrt{34} }= <\frac{ 3 }{ \sqrt{34} },\frac{ 5 }{ \sqrt{34} }>\]

Answer 6

no, we just use algebraic way to get unit vector

Answer 7

Ok, So how would we compute them with v1 and v2 not with the unit vectors
