Orthogonal Transformation and condition

  1. Dec 31, 2008 #1
    Hi there!
    In order to proof the orthogonal condition aijaik=[tex]\delta_{jk}[/tex] j,k=1,2,3
    I write the invariance of the length of a vector in two coordinate systems:
    Using the linear transformation:
    the first term becomes:

    My question is: why can't I write
