Let u= < 4,3> . find the unit vector in the direction of u, and write your answer in component form.

The component form of the unit vector in the direction of u will be:

 and this can be determine by using the unit vector formula.

Given :

u = <4,3>

Unit vector formula will be use to determine the unit vector in the direction of u, that is:

    ----- (1)

So, the magnitude of u will be:

Now, put the value of and  in equation (1).

So, the component form of the unit vector in the direction of u will be:
