Question

how to calculate direction of 4d vector

Answer 1

Divide it by its magnitude.

Answer 2

^ which is the same as finding the direction of any vector in any dimension if I am right

Answer 3

for example <1,2,3,4> what to do

Answer 4

i m assuming \[\frac{ 1 }{ 30 }<1,2,3,4>\] will be direction of this vector??? @wio

Answer 5

The magnitude is 30?

Answer 6

oops sqrt(30)

Answer 7

That looks right.

Answer 8

\[
\frac{\sqrt{30}}{30}
\]

Answer 9

can yoou explain me graphicaly how is this a direction and related to vector?

Answer 10

We have to use a unit vector to describe the direction of a vector, since it takes away the magnitude of the vector

Answer 11

you will need to use 4 directional cosines to describe the directio i think, like u do in 3d

Answer 12

ohk...so basically unit vector is the direction of vector v

Answer 13

oh how? so unit vector isn't right?

Answer 14

unit vector is the vector wid magnitude of 1, along the direction of given vector.

Answer 15

so it is direction, isnt it!!! i m confused
