Ambiguity in Theorem 4.3. Apostol's book

63 Views Asked by At

In Theorem 4.2. of Apostol's Analytic Number Theory Abel's identity is introduced. Theorem 4.3. is an application for the identity and claims the equality $$\theta(x) = \pi(x) \log (x) - \int_{3/2}^x \dfrac{\pi(t)}{t} dt = \pi(x) \log (x) - \int_2^x \dfrac{\pi(t)}{t} dt,$$ which is a result of taking $y=3/2$ in Abel's identity but if we take $y=2$ we will have $$\theta(x) = \pi(x) \log (x) - \pi(2) \log (2) - \int_2^x \dfrac{\pi(t)}{t} dt \ne \pi(x) \log (x) - \int_2^x \dfrac{\pi(t)}{t} dt,$$ since integral of a single point is zero.

How this contradiction is resolved?
