Find the unit vector in the direction of the vector .
The given vector is a → = i ^ + j ^ + 2 k ^ .
Magnitude of vector a → is,
| a → | = 1 2 + 1 2 + 2 2 = 6
The unit vector in direction of a → is given as,
a ^ = a → | a → | = i ^ + j ^ + 2 k ^ 6 = 1 6 i ^ + 1 6 j ^ + 2 6 k ^
Thus, unit vector in direction of a → is 1 6 i ^ + 1 6 j ^ + 2 6 k ^ .
The given vector is
Magnitude of vector
The unit vector in direction of
Thus, unit vector in direction of
and
,
