Ol=E1 lista, pe=E7o ajuda, n=E3o achei uma sa=EDda anal=EDtica.
A(n) =3D A(n-1) + ( D(n) - A(n-1) )/n
onde:
D(n) =3D sinal( I(n) )*R=20
e
I(n) =3D I(n-1) + V - D(n-1)
Mostrar que A(n) converge para V quando |V| < R
Considerar:=20
A(0) =3D D(0) =3D I(0) =3D 0.
n inteiro, R constante real positiva, V constante real.
sinal() retorna 1 para argumento positivo, -1 para argumento negativo e =
0 para argumento nulo.
Obrigado, Ojesed.
