Magnitude of v= 2
Angle= v in the direction i+3j

Answered by bobpursley
so the direction vector is

(i+3j)/sqrt10

The i component of
2@directionabove= 2/sqrt10
and the y component is
1*3/sqrt10

Thanks!

I have a question: Is the length of a vector the same thing as its magnitude?
Answered by Damon
yes
Answered by bobpursley

y component= 2*3/sqrt10
