Question

sejam matrizes quadradas A e B de ordem de 2 definidas por :
A=(aij)2x2 tal que aij =i/2 +j/2
B=(bji)tal que bji=2i-j

Answer 1

·$A = \left[\begin{array}{ccc}a11&a12\\a12&a22\end{array}\right] = \left[\begin{array}{ccc}1/2+1/2&1/2+2/2\\2/2+1/2&2/2+2/2\end{array}\right] =$$A = \left[\begin{array}{ccc}1&1,5ou3/2\\1,5ou3/2&2\end{array}\right]$

$B = \left[\begin{array}{ccc}b11&b12\\b21&b22\\\end{array}\right] = \left[\begin{array}{ccc}2x1-1&2x1-2\\2x2-1&2x2-2\end{array}\right] =$
$B = \left[\begin{array}{ccc}1&0\\3&2\end{array}\right]$·
