Question

Construa as Matrizes

A) (aij)2x2 , Onde se i=J , i x J
se i≠ J , i+J

&


B) (bij)2x2 , onde
se i>j , i-j
se i < j , i +j
se i=j , i-j

em Seguida determine

A) A+B

B) A-B

Answer 1

Vamos lá,

A) (aij)2x2

$A = \left[\begin{array}{ccc}a11&a12\\a21&a22\end{array}\right]$

$A = \left[\begin{array}{ccc}1&3\\3&4\end{array}\right]$

B) (bij)2x2

$B = \left[\begin{array}{ccc}a11&a12\\a21&a22\end{array}\right]$

$B = \left[\begin{array}{ccc}0&3\\1&0\end{array}\right]$

Em seguida

A) $\left[\begin{array}{ccc}1&3\\3&4\end{array}\right]  - \left[\begin{array}{ccc}0&3\\1&0\end{array}\right] = \left[\begin{array}{ccc}1&0\\2&4\end{array}\right]$

B) $\left[\begin{array}{ccc}1&3\\3&4\end{array}\right] - \left[\begin{array}{ccc}0&3\\1&0\end{array}\right] = \left[\begin{array}{ccc}1&0\\2&4\end{array}\right]$

Espero ter ajudado!
