Comment 3 for bug 817709

Thanks for your answer.

You are right, the π is there. I think I couldn't find it because in the default font, it looks like a box with the bottom part removed. Usually, it is typeset more curvy.

Thanks for the hint with Ctrl+I, it works well. However, it is a hidden feature and I think it is not accessible enough. There should be a non-shortcut way to activate this function. Either a menu item or a button "^-1". The easiest solution would be to add arcsin, ... to the list of extra functions under the "f(x)" button in advanced mode (possibly in a submenu "trigonometry").

This is the default calculator in Ubuntu, so on a fresh system, I would like it to "just work", i. e. it should be intuitive and there should be no need to read the documentation first. (Although this is never a bad idea.)

Allowing arcsin to be entered manually would be nice as well. Personally I prefer plain text input over some advanced formatting and UTF-8 characters like √ and ×. (But it seems to be done well, I can copy & past without problems.)
