SUMMARY
The discussion focuses on finding a unit vector that is perpendicular to both the vector 4i - 3j + k and the z-axis. A vector parallel to the xy-plane must have a zero z-component, making it perpendicular to the unit vector k. The algebraic condition for a vector to be perpendicular to another involves the dot product being zero. The cross product of the vectors 4i - 3j + k and k yields a vector that meets the criteria of being perpendicular to both original vectors.
