thanks for your post..^^.. i think it help me a lot. but can you explain what is the meaning of "choice of basis for the underlying space"?can u give some example? i really not very understand what is the meaning.thanks again.

Dear all, I'm a math student and i facing problem to solve these question.hope all of u can help. 1. what would be wrong with defining matrix multiplication for matrices of the same size by multiplying them entry-by-entry, as with addition and subtraction? 2. discuss the relative merits of computing determinants between cofactor expansion method and row reduction method. 3. under what conditions will a matrix be diagonalizable? Are there any cases where one can tell at a glance whether a matrix is diagonalizable? hope someone can help me...thanks a lot..
