a) Calcule A*B y B*A&lt;br /&gt;

b) Compruebe que(A+B)^^2=A^^2+B^^2&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
En Maxima, &lt;br /&gt;
a) Definimos las matrices A y B:&lt;br /&gt;
&lt;br /&gt;
 (%i1) A:matrix([1,-1],[2,-1]);&lt;br /&gt;
 (%o1) matrix([1,-1],[2,-1])&lt;br /&gt;
 &lt;br /&gt;
 (%i2) B:matrix([1,1],[4,-1]);&lt;br /&gt;
 (%o2) matrix([1,1],[4,-1])&lt;br /&gt;
&lt;br /&gt;
Calculamos el producto de A*B:&lt;br /&gt;
&lt;br /&gt;
 (%i3) A.B;&lt;br /&gt;
 (%o3) matrix([-3,2],[-2,3])&lt;br /&gt;
&lt;br /&gt;
Calculamos el producto de B*A:&lt;br /&gt;
&lt;br /&gt;
 (%i4) B.A;&lt;br /&gt;
 (%o4) matrix([3,-2],[2,-3])&lt;br /&gt;
&lt;br /&gt;
b)Calculamos en primer lugar (A+B)^^2:&lt;br /&gt;
&lt;br /&gt;
 (%i5) (A+B)^^2;&lt;br /&gt;
 (%o5) matrix([4,0],[0,4])&lt;br /&gt;
&lt;br /&gt;
y ahora A^^2+B^^2:&lt;br /&gt;
&lt;br /&gt;
 (%i6) A^^2+B^^2;&lt;br /&gt;
 (%o6) matrix([4,0],[0,4])&lt;br /&gt;
