Question

Construa as matrizes abaixo:
a) A= (aij) 1×4 tal que aij = i+j se i-j
i-j²se i+j

Answer 1

A=$\left[\begin{array}{ccc}a11\\a21\\a31\\a41\end{array}\right] = \left \{ {{aij(a11)=i+j} \atop\atop {aij(a21)=i-j\atop\atop {aij(a31= i-j ^{2}\atop\atop {aij(a41= i+j }} \right. \left[\begin{array}{ccc}a11=1+1 = 2\\a12= 2-1= 1\\a31= 3-1 ^{2}= 2\\a41= 4+1= 5 \end{array}\right]$
