Maths - sin, tan and cos are all factors of the rotation of a circle, hence pi being on there. I'm not a mathematician, I just watch standup maths and can recommend his book, "love triangle" to explain this sort of stuff.

I'm really trying to do this with my daughter too - she's 7 and it's getting hard at times because she's wanting space, but I'll give her that as she wants it. Unless it is safety related of course...
With a PFY ready just outside the room with the improvised mega volt cables incase you get wise and try and bolt. And something happened to the lifts so the doors opened without the lifts being there...

people wouldn't have to masquerade as much behind legitimate business.
Yes, that's the point - they'd BE a legitimate business anyway. Sadly, the concept of it being not so, is so ingrained in Western (American and British, at least) culture that even comments in support reveal an unconscious bias that's hard to overcome.

Mine is sidereal... I always said side real. Then, I learned it was (roughly) Sid air heal.
Though I did use to say Copernicus as copper knickers too.

Translation added, roughly done. Tip: modern Android devices let you press and hold the switcher, which takes a screen shot of whatever is on screen. Then, you can press the translate button that appears to translate whatever is on screen. Works with the camera too - easier than firing up Google lens or whatever.
Of course, you need all the Google gubbins to do it, but if you've got that it's really powerful.
Roughly translated:
We exorcise you, every unclean spirit, every satanic power. Every infernal invasion of adversity, every diabolical assembly and sect. Therefore, curse the dragon, make your church safe to serve you in freedom. We ask you. Listen to us.
No worries... It's a pretty obscure math joke anyway :-P
