The direction of the unit vector U is along the bearing of 30°. The basic idea behind finding the negative vector of a given vector is to find the two components of the given vector (i.e., the vector’s magnitude and the direction) and then find a vector of the same length that points in the opposite direction. After finding the components for the vectors A and B, these components may be just simply added to find the components of the resultant vector R. The components fully specify the resultant of the vector addition, but it is often desirable to put the resultant in polar form. The magnitude is a measurement of the size of the vector.
