"WebOct 30, 2024 · First. Since we know that 1 x diverges, we can write 1 x ln x < 1 x and thus the integral diverges, i.e it does not converge. Second. The integral converges by definition if the limit lim x → 1 ∫ 0 x 1 x ln x d x exists and is finite. But since the limit lim x → 1 ( ( ln ( ln 1) − ln ( ln 0) is not defined the integral does not converge. " - How do you know if an integral diverges
