| Nov 7, 2019 at 20:52 | comment | added | Martin Sleziak | Just a short comment regarding the choice of tag. The tag (abstract-algebra) is deprecated on MO, see the tag-info. And it is recommended to use one of the top-level tags: See: Why are MO tags formatted as they are? and Frequently asked questions about tagging on MathOverflow. | |

| Nov 7, 2019 at 20:32 | comment | added | Anixx | @Wojowu yes, but the connection between logarithm and inverse trigonometric functions is quite expected. In this case we have connection between logarinthm and trigonometric function (not inverse). | |
| Nov 7, 2019 at 20:31 | comment | added | Wojowu | For the record, $\frac{i}{2}\ln\left(\frac{i+z}{i-z}\right)=\tan^{-1}(z)$. | |
