Orthogonality and Orthonormality

  • Lorenzo Robbiano


We are used to thinking of orthogonal coordinate systems as the most interesting and most useful. This habit comes from studying the graphs of functions in the plane or in space. Is the same thing also true in ℝn? In this chapter we will try to justify the reason for this perception and also to respond to the question above.
