Afisherman notices that wave crests pass the bow of his anchored boat every 4.4 s. he measures the distance between two crests to be 9.5 m. how fast are the waves traveling?

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.
