I need to find the unit vector of v = (3,1). see following post for answer.
\[1\div \sqrt{10}\]
unit vector =v/|v|=(3/sqrt10,1/sqrt10)
hold on i'm trying to figure out how to use this latex editor
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 /?
unit vector =[3,1]/sqrt(3^2+1^2) =[3,1]/sqrt(10)
