Question About Pi
How do we know that Pi is an irrational number? I.e. a number that cannot be represented as terminating or repeating decimals.
How do we know that Pi doesn't end after 10 trillion decimal places or just start repeating the previous 10 trillion (or whatever)?
Can it be proved that Pi is irrational? How does one go about proving that a ratio such as Pi is definitely irrational?
