How can pi be infinite if the circumference of a circle is finite?
>>
>>8492722
Same thing with a right angled triangle with two sides of 1, it has a hypotenuse of sqrt(2) which is infinite but the actual side is finite
>>
pi is irrational not infinite, 0>pi>4, so pi is finite.

Because of its infinite resolution.

How can pi be infinite when it is less than four?

0.999... Is infinite too

What precisely is an angle??

The problem is that defining an angle correctly requires calculus. This is a point
implicit in Archimedes’ derivation of the length of the circumference of a circle, using
an infinite sequence of successively refined approximations with regular polygons. It is
also supported by the fact that The Elements [Euclid] does not try to measure angles,
with the exception of right angles and some related special cases. Further evidence can
be found in the universal reluctance of traditional texts to spell out a clear definition of
this supposedly ‘basic’ concept.

>>8492760
.999... =1, so 1 is also infinite
>>
>>8492893
Actually this is how we prove 0.999...=1.

Prop 1: 0.999... is infinite
Prop 2: 1=1.000..., ergo 1 is infinite

We know that infinite quantities equal each other, so 0.999...=1.

>>8492893
By your logic 1=1.00000....0001 then you can further that forever until you reach 1 = infinity.

1/3 is represented by .3333333333333333333333
2/3 is represented by .6666666666666666666666
3/3 is represented by .9999999999999999999999

Therefore .9999999999999999999999 is equal to 1
>>
>>8492906
While 0.999... is definitely 1, 1.000...1 isn't, because the 1 at the end means that there is a finite amount of zeros between the decimal point and the last 1. 0.999... is 1 only because there are infinite 9s following the decimal point.

>>8492739
>0>pi>4
0 > 4.
there are people on /sci/ RIGHT NOW that LITERALLY believe 0 is GREATER THAN 4.

Pi can be thinked of as the relation between the diameter and the length of the contour of a circunference. The diameter fits 3,14... times in the length of the contour of the circunference. Pi is irrational, that means that it has infinite decimal numbers, but it is finite. You can approximate it's value, but you will never be able to represent it at its full extent.
All you will know is
3,13 < 3,14 < 3,15
3,140 < 3,141 < 3,142
3,1414 < 3,1415 < 3,1416
and so on.

Are you sure it is finite?
>>
Isn't there a calculation now that allows you to enter the digit you want and out it will pop? Like I want the ten thousand digit of pi and enter 10,000 in the calculation and out pops 7.

No, you can prove that the approximation you are using never reach the circumference.

This is one of the cases where, even if two functions are very close, their derivatives aren't.

Who have told you that C or d are rational?
