All vectors are in rn. check the true statements below:
(a) the orthogonal projection of y onto v is the same as the orthogonal projection of y onto cv whenever c≠0.
(b) if the columns of an m×n matrix a are orthonormal, then the linear mapping x→ax preserves lengths.
(c) if a set s={} has the property that ui⋅uj=0 whenever i≠j, then s is an orthonormal set.
(d) an orthogonal matrix is invertible.
(e) not every orthogonal set in rn is a linearly independent set.
