WitrynaThis improper integral diverges but the Cauchy principal value ex-ists. Indeed for the improper integral we have Z 1 1 dx x = lim u!0;l!0 Z u 1 dx x + Z 1 l dx x = lim u!0;l!0 lnu lnl: If we let uto zero rst then we get 1 but if we let lgo to zero rst we get 1. In fact we can get any limit we please, if we coordinate l and u. http://www.kevinhouston.net/blog/2013/03/what-is-the-best-proof-of-cauchys-integral-theorem/ therabel belgique

It is related to Abel's test for the convergence of an ordinary series of real numbers, and the proof relies on the same technique of summation by parts . The test is as follows. sign language with baby
