Ol=E1 a todos!
=20
Pe=E7o ajuda neste problema:
=20
=93Considerando o sistema linear com as duas seguintes equa=E7=F5es:
=20
(log a)x + [(sen b)^2]y =3D 1
[log(a+b)x + [(cos b)^2]y =3D 2
=20
Com a > 0 e b > 0. Prove que se ([log(base 9){b/a}]^cos2x) < 1, (Pi/4) < =
x <
(3Pi/4), ent=E3o o sistema admite uma =FAnica solu=E7=E3o.=94
=20
Obs.: l=EA-se =93([log(base 9){b/a}]^cos2x) < 1=94 como: logaritmo de b =
sobre a
na base 9, elevado ao co-seno de 2x, menor que um.
=20
Desde j=E1 agrade=E7o!
