## anonymous 4 years ago I need to find the unit vector of v = (3,1). see following post for answer.

1. anonymous

$1\div \sqrt{10}$

2. anonymous

unit vector =v/|v|=(3/sqrt10,1/sqrt10)

3. anonymous

hold on i'm trying to figure out how to use this latex editor

4. anonymous

I can't figure out how to write fractions with the equation editor

there is no unit vector of a point if you want to find the unit vector then v should be a vector it must be written as v=[3,1]

محمد you're right, I made a mistake

can you write fractions with the latex, or do you just use /?
