Question

FIND THE UNIT VECTOR OF VECTOR P=4ICAPS+5JCAPS-KCAPS

Answer 1

let A unit vector= A vector/ magnitude of A vector.
=4 i cap + 5 j cap - 1 k cap/ √42
where |A|= √(4)^2 + (5)^2 + (-1)^2
=√42

Answer 2

Answer:

let A unit vector= A vector/ magnitude of A vector.

=4 i cap + 5 j cap - 1 k cap/ √42

where |A|= √(4)² + (5)² + (-1)²

=√42
