That would be very unusual (unorthodox) definition of Pi though.

- TheOtherHobbes 5y agoJust because it's the same number doesn't mean it's the same relationship. Any definition that relies on trig (sometimes disguised as trig expansion) assumes the existence of a flat Euclidean space - which is a convenient mathematical abstraction in real-world terms, but not required in the general case. Most everyday physics assumes a flat space, so it's not surprising certain constants fall out of this. There are more complex and interesting definitions which rely on relationships defined by group theory. I don't know enough about those to say if they're just more complex ways to operate in a flat space, or more complex ways to disguise simple trig expansions, or if they're completely independent, or if something else is going on.
- rocqua 5y agoThat's not fully true. You can get trig functions without any kind of geometry.
