Question

if vector A=2i^+4j^-4k^,then the unit vector in direction of vector A is
​

Answer 1

Answer:

Unit vector in the direction of A is A/|A|

=1/6(2 i+ 4 j - 4 k)

Answer 2

Answer:

Â= [2i^ + 4j^ + 4k^]\6

Explanation:

we can find unit vector by dividing the vector by its own absolute value (mod of vector)

which means

A^ will be equal to A/|A|

here |A| = √(2^2 + 4^2 + 4^2) = √36 = 6
