How are irrational numbers converted into fractions? Such as sin(pi/4) = sqrt2/2
-
Everyone knows the digits that make Pi, just not the order that they go in.
-
ELI5: If the expansion of pi is infinite and has been shown to contain every possible sequence of numbers, how can it be non-repeating?

Eli5 How are mathmatical concepts like pi discovered?
-
A formula for pi I made. Inspired by the Monte-Carlo method from von Neumann. Instead of placing points at random it places them at a fixed interval, on a grid, and makes that grin infinitely thin.

Solving for feta between -pi radians and pi radians
-
Does pi contain every possible combination of numbers?
-
Why does this problem equal (π²/72) and not (π²/18)?
-
ELI5: How do we know that pi (or e, for that matter) is infinite and non-repeating?
-
Does Pi illustrate an error in our fundamental use of mathematics, and does calculating the ratio behave the same way (random, non-repeating, non-terminating) in other bases (ie: Binary or Base 16)?

For funzies, 12” diameter so r=6 and pi/2 and maybe centimeter thick. How many fun function can we set up here? I’m thinking area would be easy.

This is a problem in my textbook, not homework or test or anything. I just can't for the life of me wrap my head around how they came to the conclusion that delta d is equal to pi times h or the "height" of the circle.…
