3. [30%] A unit vector is a vector whose magnitude is 1. Unit vectors are used in many areas of engineering and physics. A unit vector can be calculated from any vector by dividing the vector by the magnitude of the vector. A three-dimensional unit vector in the direction of vector v = xi + I y + zk can be calculated as u = xi + yj + zk x2 + y2 + z2 Write a script file that accepts a three-dimensional vector in rectangular coordinates and calculates the unit vector
