Find the unit vec

Answer :

We have,



Since, unit vector is needed to be found in the direction of the sum of vectors and .


So, add vectors and .


Let,



Substituting the values of vectors and .






We know that, a unit vector in a normed vector space is a vector (often a spatial vector) of length 1.


To find a unit vector with the same direction as a given vector, we divide by the magnitude of the vector.


For finding unit vector, we have the formula:



Substitute the value of .



Here, .






Thus, unit vector in the direction of sum of vectors and is .
