Is anyone here doing anything special for Pi day this year?
You must log in or register to comment.
Me and my European homies will celebrate pi day on the 22nd of July, as Archimedes intended
Is 22/7 that approximation of pi people sometimes do?
22/7 is 3.14 if you round it so yes
My math teacher always used to teach that to us, but we learned that it’s not a very good approximation of Pi when she tried to grade our work with a calculator instead of the answer sheet. All of us asked her why we got Ds on the test and she went back and realized many of us got it right according to the book but when she used a calculator it was different because 22/7 is bad approximation.
355/133 is much better. accurate to seven digits i think. it’s my favourite approximation :)
Lunar eclipse pi!
I celebrated yesterday
I celebrated by watching YouTube
