Question

Let U <1,3>. Find a Vector V, such that V has some direction angle as U and ||V||= 1

Answer 1

if U is 5 units long, then dividing it by 5 produces 5 unit vectors

if U is 14 units long, then dividing it by 14 produces 14 unit vectors

if U is 152 units long, then dividing it by 152 produces 152 unit vectors

if U is k units long, then dividing it by k produces k unit vectors

Answer 2

in other words, V = U/k

Answer 3

What he's saying is that the slope of your line will be 3 and it will be 1 unit long.
