Title: Add more math functions and unite them with Trig

The first commit adds more math functions and groups them with trigonometry functions as `Math` module, i.e. `Trig` is merged into `Math`.

The second commit adds those span elements around some arguments in helpers which are missing them. I know it's not really related to math functions, but I wanted to squeeze those in also :)
