Arnold J. Insel,Illinois State University,Normal,IL. The College Mathematics Journal,May 1989,Volume 20,Number 3,pages 235–237. In this capsule,we give a direct proof that the Arctangent is an integral of 1 ys1 x2 d. 1.
The integral of arctan is the integration of tan inverse x, which is also called the antiderivative of arctan, which is given by ∫tan -1 x dx = x tan -1 x - ½ ln |1+x 2 | + C, where C is the constant of integration. The integral of arctan can be calculated using the integration by parts method.
24 kwi 2019 · Here $\operatorname{Cl_2}(z)$ denotes the Clausen Function and $\operatorname{Li}_2(z)$ the Dilogarithm, or Spence's Function. Recalling the integral representation of the Clausen Function one can verify the result by direct differentation using the Fundamental Theorem of Calculus and the chain rule.
