Matrix and lineear transformations

  1. Aug 23, 2008 #1
    i need some help with this question -

    lets say if A =

    |val1 val2 |
    |val3 1 |

    what would AA^t equal?


    AA^t and A^T.T are symmetrical. is this true for any 2x2 matrix?

    thanks in advance

    What are val1,val2,val3? If they are arbitrary values, try writing out the matrix multiplication and see if you can notice anything special about the matrix obtained. Same approach for the 2nd question.
