Hurrr which equations represent the relationship between wavelength and frequency for a sound wave? check all that apply. v = xf = vf f = xv x = v\f x = f\v f = v\x f = x\v (is not an x but is the letter the looks similar to the symbol on th question )

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
