Examples 7.1.9(c):
In a previous example we have shown that U(f, P) = 1 and L(f, P) = 0, regardless of the partition. Therefore:I*(f) = 1 and I*(f) = 0Therefore, the Dirichlet function is not integrable over the interval [0, 1].
I*(f) = 1 and I*(f) = 0Therefore, the Dirichlet function is not integrable over the interval [0, 1].
