WebHowever, for any set of linearly independent vectors (all wavefunctions of a Hamiltonian are linearly independent) there exists linear combinations of them that are orthogonal which can be found through the Gram–Schmidt procedure. Thus one can choose the vectors to be linearly independent. Share Cite Improve this answer Follow WebTwo vectors x , y in R n are orthogonal or perpendicular if x · y = 0. Notation: x ⊥ y means x · y = 0. Since 0 · x = 0 for any vector x , the zero vector is orthogonal to every vector in R n . We motivate the above definition using the law of cosines in R 2 . east granby high school athletics
