Find the unit vector in the direction of (4,-4). Write your answer in component form. Do not approximate any numbers in your answer.

Step-by-step explanation:

The unit vector for a nonzero vector, say u, in the direction of u is given by:

û =             ---------------(i)

Where;

|u| = magnitude of vector u

From the question;

u = (4, -4)

First let's calculate the magnitude of u as follows;

|u| =

|u| =

|u| = =

Now, substitute u and |u| into equation (i) as follows;

û =

û =

û =

Therefore, the unit vector is

tangent
